# Custom Toolbar

If you want to use custom toolbar but still want the support of this libray
You can use the `QuillBaseToolbar` which is the base for the `QuillToolbar`

> If you are using the toolbar buttons like `QuillToolbarHistoryButton`, `QuillToolbarToggleStyleButton` in the somewhere like the the custom toolbar 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:

```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;
              return [
                QuillToolbarHistoryButton(
                  controller: controller,
                  options: const QuillToolbarHistoryButtonOptions(
                      isUndo: true),
                ),
                QuillToolbarHistoryButton(

          ),
        ),
      )
    ],
  ),
)
```

if you want more customized toolbar feel free to create your own and use the `controller` to interact with the editor. checkout the `QuillToolbar` and the buttons inside it to see an example of how that will works
