StacFlexible class

A Stac model representing Flutter's Flexible widget.

Controls how a child of a Row, Column, or Flex flexes (expands or contracts) to fill the available space along the main axis. Use fit to specify whether the child can be smaller than the space allocated by its flex factor.

{@tool snippet} Dart Example:

StacRow(children: const [
  StacFlexible(flex: 1, child: StacText(data: 'Left')),
  StacFlexible(flex: 2, fit: StacFlexFit.tight, child: StacText(data: 'Right')),
])

{@end-tool}

{@tool snippet} JSON Example:

  "children": [
    {"type": "flexible", "flex": 1, "child": {"type": "text", "data": "Left"}},
    {"type": "flexible", "flex": 2, "fit": "tight", "child": {"type": "text", "data": "Right"}}
  ]
