Constrained Scrollable Views

Set of useful scrollable views includes ConstrainedScrollView, ScrollableColumn, and ScrollableRow.

• ConstrainedScrollView is a combination of LayoutBuilder and SingleChildScrollView.
• ScrollableColumn is Column wrapped by ConstrainedScrollView.
• ScrollableRow is Row wrapped by ConstrainedScrollView.

Usage

Example of using ConstrainedScrollView:

ConstrainedScrollView(
  padding: const EdgeInsets.all(8),
  physics: const BouncingScrollPhysics(),
  constraintsBuilder: (constraints) => BoxConstraints(
    minWidth: constraints.maxWidth,
    minHeight: constraints.maxHeight,
  ),
  child: const Center(
    child: Text('ScrollView value'),
  ),
)

Example of using ScrollableColumn:

ScrollableColumn(
  padding: const EdgeInsets.all(8),
  physics: const BouncingScrollPhysics(),
  constraintsBuilder: (constraints) => BoxConstraints(
    minHeight: constraints.maxHeight,
  ),
  children: [
    for (var i = 0; i <= 100; i++)
      Padding(
        padding: const EdgeInsets.all(4),
        child: Text('Column value: $i'),
      ),
  ],
)

Example of using ScrollableRow:

ScrollableRow(
  padding: const EdgeInsets.all(8),
  physics: const BouncingScrollPhysics(),
  constraintsBuilder: (constraints) => BoxConstraints(
    minWidth: constraints.maxWidth,
  ),
  children: [
    for (var i = 0; i <= 100; i++)
      Padding(
        padding: const EdgeInsets.all(4),
        child: Text('Row value: $i'),
      ),
  ],
)
