After creating a [State] object and before calling [initState], the framework "mounts" the [State] object by associating it with a [BuildContext].

<itemvalue="Unhandled Exception: This widget has been unmounted, so the State no longer has a context (and should be considered defunct). Consider canceling any active work during "dispose" or using the "mounted" getter to determine if the State is still active."/>
<itemvalue="A general-purpose widget for building animations. [AnimatedBuilder] is useful for more complex widgets that wish to include an animation as part of a larger build function. To use [AnimatedBuilder], construct the widget and pass it a builder function. For simple cases without additional state, consider using [AnimatedWidget]. {@youtube 560 315 https:www.youtube.comwatch?v=N-RiyZlv8v8} Despite the name, [AnimatedBuilder] is not limited to [Animation]s, any subtype of [Listenable] (such as [ChangeNotifier] or [ValueNotifier]) can be used to trigger rebuilds. Although they have identical implementations, if an [Animation] is not being listened to, consider using a [ListenableBuilder] for better readability."/>
<itemvalue="How wide to make edges drawn when [style] is set to [PaintingStyle.stroke]. The width is given in logical pixels measured in the direction orthogonal to the direction of the path. Defaults to 0.0, which correspond to a hairline width."/>

The sort function is not guaranteed to be stable, so distinct objects that compare as equal may occur in any order in the result: ```dart final numbers = <String>['one', 'two', 'three', 'four']; numbers.sort((a, b) => a.length.compareTo(b.length)); print(numbers); [one, two, four, three] OR [two, one, four, three]"/>

<itemvalue="The fill for drawing the icon. Requires the underlying icon font to support the `FILL` [FontVariation] axis, otherwise has no effect. Variable font filenames often indicate the supported axes. Must be between 0.0 (unfilled) and 1.0 (filled), inclusive. Can be used to convey a state transition for animation or interaction.

[opticalSize], for controlling optical size."/>
<itemvalue="The size of the icon in logical pixels. Icons occupy a square with width and height equal to size. Defaults to the nearest [IconTheme]'s [IconThemeData.size]. If this [Icon] is being placed inside an [IconButton], then use [IconButton.iconSize] instead, so that the [IconButton] can make the splash area the appropriate size as well.

<itemvalue="To make sure that listeners removed during this iteration are not called, we set them to null, but we don't shrink the list right away. By doing this, we can continue to iterate on our list until it reaches the last listener added before the call to this method. To allow potential listeners to recursively call notifyListener, we track the number of times this method is called in _notificationCallStackDepth. Once every recursive iteration is finished (i.e. when _notificationCallStackDepth == 0), we can safely shrink our list so that it will only contain not null listeners."/>
