* Dispose ValueNotifier of cursor controller

* Remove getter for final operator

A getter for a final variable makes no sense, because the variable
cannot be reassigned. It is better to remove the unnecessary getter
and make the variable public.

* Add comments to cursor class

* Remove null exception when a disposed controller is set

* Disallow lines longer than 80 characters

* Don't create a lambda when a tear-off will do

* Move ResponsiveWidgets to example folder

This widget has nothing to do with the library and is only used in
the example, so it is moved to the example.

* Fix null exception

* Remove exception when widget is not mounted

* Fix exception when rect is not a number

* Fix paste (#236)

closes #235.

* use ceil instead of floor to make sure won't cause overflow

* Fix example project Podfile (#241)

* Show arrow indicator on toolbar (#245)

* Add color parameter to Toolbar and ImageButton

In addition, change these widgets to stateless widgets, since these
widgets do not have a state and thus stateful is superfluous.

* Fix paste bug

* Remove extraneous toolbar dividers in certain configuration

Closes #193.

* Upgrade version to 1.3.2

* Format code

* Bump file_picker to 3.0.2+2

With version 3.0.2 `name` of the file_picker library becomes
non-nullable, so a warning was issued for users who had already
used version 3.0.2, as we still assumed that `name` is nullable.
Increasing the version and removing the exclamation mark removes
the warning.

* Fix a bug that Embed could be together with Text (#249)

* Fix #242 (#254)

* Upgrade to 1.3.3

* Format code
