|
||||
## from 7.0.0 to 8.0.0 |
||||
|
||||
We have refactored a lot of the base code to allow you to customize everything you want, and it allow us to add new configurations very easily using inherited widgets without passing configurations all over the constructors everywhere which will be very hard to test, fix bugs, and maintain |
||||
|
||||
1. Passing the controller |
||||
|
||||
The controller code (should be the same) |
||||
```dart |
||||
QuillController _controller = QuillController.basic(); |
||||
``` |
||||
|
||||
**Old code**: |
||||
```dart |
||||
|
||||
Column( |
||||
children: [ |
||||
QuillToolbar.basic(controller: _controller), |
||||
Expanded( |
||||
child: QuillEditor.basic( |
||||
controller: _controller, |
||||
readOnly: false, // true for view only mode |
||||
), |
||||
) |
||||
], |
||||
) |
||||
|
||||
``` |
||||
|
||||
**New code**: |
||||
|
||||
```dart |
||||
QuillProvider( |
||||
configurations: QuillConfigurations( |
||||
controller: _controller, |
||||
sharedConfigurations: const QuillSharedConfigurations(), |
||||
), |
||||
child: Column( |
||||
children: [ |
||||
const QuillToolbar(), |
||||
Expanded( |
||||
child: QuillEditor.basic( |
||||
configurations: const QuillEditorConfigurations( |
||||
readOnly: false, // true for view only mode |
||||
), |
||||
), |
||||
) |
||||
], |
||||
), |
||||
) |
||||
``` |
||||
|
||||
The `QuillProvider` is inherited widget which allow you pass configurations once and use them in the children of it. here we are passing the `_controller` once in the configurations of `QuillProvider` and the `QuillToolbar` and `QuillEditor` will get the `QuillConfigurations` internally, if it doesn't exists you will get an exception. |
||||
|
||||
we also added the `sharedConfigurations` which allow you to configure shared things like the `Local` so you don't have to define them twice, we have removed those from the `QuillToolbar` and `QuillEditor` |
||||
|
||||
2. The QuillToolbar buttons, we have renamed almost all the buttons, examples: |
||||
- `QuillHistory` to `QuillToolbarHistoryButton` |
||||
- `IndentButton` to `QuillToolbarIndentButton` |
||||
|
||||
and they usually have two parameters, `controller` and `options`, example of the type for the buttons |
||||
- `QuillToolbarHistoryButton` have `QuillToolbarHistoryButtonOptions` |
||||
- `QuillToolbarIndentButton` have `QuillToolbarIndentButtonOptions` |
||||
- `QuillToolbarClearFormatButton` have `QuillToolbarClearFormatButtonOptions` |
||||
|
||||
All the options have parent `QuillToolbarBaseButtonOptions` which have commons things like |
||||
|
||||
```dart |
||||
/// By default it will use a Icon data from Icons which comes from material |
||||
/// library for each button, to change this, please pass a different value |
||||
/// If there is no Icon in this button then pass null in the child class |
||||
final IconData? iconData; |
||||
|
||||
/// To change the the icon size pass a different value, by default will be |
||||
/// [kDefaultIconSize] |
||||
/// this will be used for all the buttons but you can override this |
||||
final double globalIconSize; |
||||
|
||||
/// To do extra logic after pressing the button |
||||
final VoidCallback? afterButtonPressed; |
||||
|
||||
/// By default it will use the default tooltip which already localized |
||||
final String? tooltip; |
||||
|
||||
/// Use custom theme |
||||
final QuillIconTheme? iconTheme; |
||||
|
||||
/// If you want to dispaly a differnet widget based using a builder |
||||
final QuillToolbarButtonOptionsChildBuilder<T, I> childBuilder; |
||||
|
||||
/// By default it will be from the one in [QuillProvider] |
||||
/// To override it you must pass not null controller |
||||
/// if you wish to use the controller in the [childBuilder], please use the |
||||
/// one from the extraOptions since it will be not null and will be the one |
||||
/// which will be used from the quill toolbar |
||||
final QuillController? controller; |
||||
``` |
||||
|
||||
The `QuillToolbarBaseButtonOptions is`: |
||||
/// The [T] is the options for the button, usually should refresnce itself |
||||
/// it's used in [childBuilder] so the developer can custmize this when using it |
||||
/// The [I] is extra options for the button, usually for it's state |
||||
```dart |
||||
@immutable |
||||
class QuillToolbarBaseButtonOptions<T, I> extends Equatable |
||||
``` |
||||
|
||||
Example for the clear format button: |
||||
|
||||
```dart |
||||
class QuillToolbarClearFormatButtonExtraOptions |
||||
extends QuillToolbarBaseButtonExtraOptions { |
||||
const QuillToolbarClearFormatButtonExtraOptions({ |
||||
required super.controller, |
||||
required super.context, |
||||
required super.onPressed, |
||||
}); |
||||
} |
||||
|
||||
class QuillToolbarClearFormatButtonOptions |
||||
extends QuillToolbarBaseButtonOptions<QuillToolbarClearFormatButtonOptions, |
||||
QuillToolbarClearFormatButtonExtraOptions> { |
||||
const QuillToolbarClearFormatButtonOptions({ |
||||
super.iconData, |
||||
super.afterButtonPressed, |
||||
super.childBuilder, |
||||
super.controller, |
||||
super.iconTheme, |
||||
super.tooltip, |
||||
this.iconSize, |
||||
}); |
||||
|
||||
final double? iconSize; |
||||
} |
||||
|
||||
``` |
||||
|
||||
The base for extra options: |
||||
```dart |
||||
@immutable |
||||
class QuillToolbarBaseButtonExtraOptions extends Equatable { |
||||
const QuillToolbarBaseButtonExtraOptions({ |
||||
required this.controller, |
||||
required this.context, |
||||
required this.onPressed, |
||||
}); |
||||
|
||||
/// if you need the not null controller for some usage in the [childBuilder] |
||||
/// then please use this instead of the one in the [options] |
||||
final QuillController controller; |
||||
|
||||
/// if the child builder you must use this when the widget tapped or pressed |
||||
/// in order to do what it expected to do |
||||
final VoidCallback? onPressed; |
||||
|
||||
final BuildContext context; |
||||
@override |
||||
List<Object?> get props => [ |
||||
controller, |
||||
]; |
||||
} |
||||
``` |
||||
|
||||
which usually share common things, it also add extra property which was not exsisting, which is `childBuilder` which allow to render custom widget based on the state of the button and the options of it |
||||
|
||||
```dart |
||||
QuillToolbar( |
||||
configurations: QuillToolbarConfigurations( |
||||
buttonOptions: QuillToolbarButtonOptions( |
||||
clearFormat: QuillToolbarClearFormatButtonOptions( |
||||
childBuilder: (options, extraOptions) { |
||||
return IconButton.filled( |
||||
onPressed: extraOptions.onPressed, |
||||
icon: const Icon( |
||||
CupertinoIcons.clear // or options.iconData |
||||
), |
||||
); |
||||
}, |
||||
), |
||||
), |
||||
), |
||||
), |
||||
``` |
||||
|
||||
the `extraOptions` usually contains the state variables and the evenets that you need to trigger like the `onPressed`, it also has the end context and the controller that will be used |
||||
while the `options` has the custom controller for each button and it's nullable because there could be no custom controller so we will just use the global one |
||||
|
||||
3. The `QuillToolbar` and `QuillToolbar.basic()` factory constructor |
||||
|
||||
since the basic factory constructor has more options than the original `QuillToolbar` which doesn't make much sense, at least to some developers, we have refactored the `QuillToolbar.basic()` to a different widget called the `QuillToolbar` and the `QuillToolbar` has been renamed to `QuillBaseToolbar` which is the base for `QuillToolbar` or any custom toolbar, sure you can create custom toolbar from scratch by just using the `controller` but if you want more support from the library use the `QuillBaseToolbar` |
||||
|
||||
the children widgets of the new `QuillToolbar` and `QuillEditor` access to thier configurations by another two inherited widgets |
||||
since `QuillToolbar` and `QuillEditor` take the configuration class and provide them internally using `QuillToolbarProvider` and `QuillEditorProvider` |
||||
however the `QuillBaseToolbar` has a little bit different configurations so it has a different provider called `QuillBaseToolbarProvider` and it also already provided by default |
||||
|
||||
But there is one **note**: |
||||
> If you are using the toolbar buttons like `QuillToolbarHistoryButton`, `QuillToolbarToggleStyleButton` in the somewhere like the the custom toolbar (using `QuillBaseToolbar` or any custom widget) then you must provide them with `QuillToolbarProvider` inherited widget, you don't have to do this if you are using the `QuillToolbar` since it will be done for you |
||||
> |
||||
|
||||
Example of custom toolbar: |
||||
|
||||
```dart |
||||
QuillProvider( |
||||
configurations: QuillConfigurations( |
||||
controller: _controller, |
||||
sharedConfigurations: const QuillSharedConfigurations(), |
||||
), |
||||
child: Column( |
||||
children: [ |
||||
QuillToolbarProvider( |
||||
toolbarConfigurations: const QuillToolbarConfigurations(), |
||||
child: QuillBaseToolbar( |
||||
configurations: QuillBaseToolbarConfigurations( |
||||
toolbarSize: 15 * 2, |
||||
multiRowsDisplay: false, |
||||
childrenBuilder: (context) { |
||||
final controller = context.requireQuillController; // new extension which is a little bit shorter to access the quill provider then the controller |
||||
|
||||
// there are many options, feel free to explore them all!! |
||||
return [ |
||||
QuillToolbarHistoryButton( |
||||
controller: controller, |
||||
options: const QuillToolbarHistoryButtonOptions( |
||||
isUndo: true), |
||||
), |

), |
||||
VerticalDivider( |

), |
||||

||||
options: const QuillToolbarToggleStyleButtonOptions( |
||||

||||
iconSize: 20, |
||||

), |
||||
VerticalDivider( |

||||
), |
||||
QuillToolbarIndentButton( |

||||
isIncrease: true, |
||||
options: const QuillToolbarIndentButtonOptions( |
||||
iconData: Icons.format_indent_increase, |
||||
iconSize: 20, |
||||
)), |
||||
QuillToolbarIndentButton( |
||||
controller: controller, |
||||
isIncrease: false, |
||||
options: const QuillToolbarIndentButtonOptions( |
||||
iconData: Icons.format_indent_decrease, |
||||
iconSize: 20, |
||||
), |
||||
), |
||||
]; |
||||
}, |
||||
), |
||||
), |
||||
), |
||||
Expanded( |
||||
child: QuillEditor.basic( |
||||
configurations: const QuillEditorConfigurations( |
||||
readOnly: false, |
||||
placeholder: 'Write your notes', |
||||
padding: EdgeInsets.all(16), |
||||
), |
||||
), |
||||
) |
||||
], |
||||
), |
||||
) |
||||
``` |
||||
|
||||
4. The `QuillEditor` and `QuillEditor.basic()` |
||||
|
||||
since the `QuillEditor.basic()` is a lighter version than the original `QuillEditor` since it has less required configurations so we didn't change much, other than configuration class, but we most inform you if you are plan on sending pull request or you are a maintainer and when you add new property or change anything in `QuillEditorConfigurations` please regenerate the `copyWith` otherwise the `QuilEditor.basic()` will not apply some configurations |
||||
|
||||
we have disabled the line numbers in the code block by default, you can enable them again using the followings: |
||||
|
||||
```dart |
||||
QuillEditor.basic( |
||||
configurations: const QuillEditorConfigurations( |
||||
elementOptions: QuillEditorElementOptions( |
||||
codeBlock: QuillEditorCodeBlockElementOptions( |
||||
enableLineNumbers: true, |
||||
), |
||||
), |
||||
), |
||||
) |
||||
``` |
||||
|
||||
5. `QuillCustomButton`: |
||||
|
||||
We have renamed the property `icon` to `iconData` for indicate it a icon data and not icon widget |
||||
```dart |
||||
QuillCustomButton( |
||||
iconData: Icons.ac_unit, |
||||
onTap: () { |
||||
debugPrint('snowflake'); |
||||
} |
||||
), |
||||
``` |
||||
|
||||
6. Using custom local for both `QuillEditor` and `QuillToolbar` |
||||
|
||||
We have added sharedConfigurations property for shared things |
||||
```dart |
||||
QuillProvider( |
||||
configurations: QuillConfigurations( |
||||
controller: _controller, |
||||
sharedConfigurations: const QuillSharedConfigurations( |
||||
locale: Locale('fr'), |
||||
), |
||||
), |
||||
child: Column( |
||||
children: [ |
||||
const QuillToolbar( |
||||
configurations: QuillToolbarConfigurations(), |
||||
), |
||||
Expanded( |
||||
child: QuillEditor.basic( |
||||
configurations: const QuillEditorConfigurations(), |
||||
), |
||||
) |
||||
], |
||||
), |
||||
) |
||||
``` |
||||
|
||||
7. Custom Size Image for other platforms (excluding web) |
||||
|
||||
We have added new properties `width`, `height`, `margin`, `alignment` for all platforms other than mobile and web for the images for example |
||||
|
||||
```dart |
||||
{ |
||||
"insert": { |
||||
"image": "https://user-images.githubusercontent.com/122956/72955931-ccc07900-3d52-11ea-89b1-d468a6e2aa2b.png" |
||||
}, |
||||
"attributes":{ |
||||
"style":"width: 50; height: 50; margin: 10; alignment: topLeft" |
||||
} |
||||
} |
||||
``` |
||||
|
||||
8. Other Improvemenets |
||||
|
||||
You don't need anything to get this done, we have used const more when possible, removed unused evenets, flutter best practices, convert to stateless widgets when possible, use better ways to listen for changes example: |
||||
|
||||
instead of |
||||
|
||||
```dart |
||||
MediaQuery.of(context).size; |
||||
``` |
||||
|
||||
we will use |
||||
```dart |
||||
MediaQuery.sizeOf(context); |
||||
``` |
||||
We also minimized the amount of rebuilds using more efficent logic and there is more. |
||||
|
||||
9. More options |
||||
|
||||
We have add more options in the extension package, for all the buttons, configurations, animations, enable and disable things |
||||
