Ability to easily expand and retract a widget collection or text

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 expandarrowstyle 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 hidearrowonexpanded 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.
