Expand Widget

This Dart package offers developers a streamlined library of Flutter widgets, useful for expanding widgets and text views, when users interact with them.

There are two main 'expand' widgets:

• Expand Child: Useful to show more widgets related to the content already visible by the user.
• Expand Text: Useful when texts can be quite big for a certain screen. It adds the ability to show the full content when the user wants to.

Features

• The ExpandIndicatorStyle parameter allows you to select various render options, related to the expand arrow itself.

• Hide the arrow widget when the view is being expanded, using the hideIndicatorOnExpand parameter.

• Custimze the arrow widget itself: color, size, padding, icon...

• You can also provide your own widget for the expand indicator, using the indicatorBuilder for both expaning widgets.

• Use custom expanding hint strings! By default, it will use the ones provided by MaterialLocalizations.

• Expand text view with swipe-down gestures, using the expandOnGesture, which by default is set to false.

• You can also customize expand animation duration and curve easilly.

• The collapsedVisibilityFactor (exclusive to the ExpandChild widget), allows the reveal of a section of the hidden content.

Example

Here is an example of a simple use of this package, featuring the ExpandChild & ExpandText widgets.

If you want to take a deeper look at the example, take a look at the example folder provided with the project.

• ExpandChild

    children: [
      OutlineButton(
        child: Text('Button1'),
        onPressed: () => print('Pressed button1'),
      ),
      OutlineButton(
        child: Text('Button2'),
        onPressed: () => print('Pressed button2'),
      ),
      OutlineButton(
        child: Text('Button3'),
        onPressed: () => print('Pressed button3'),
      ),
