[rfw] Add Flexible widget support to core widgets #173313
Description
Use case
When building dynamic layouts through RFW, developers need the ability to create flexible layouts with fine-grained control over how space is distributed among children in a Row or Column. Currently, RFW only supports:
Expanded: Always takes all available space (FlexFit.tight)- No option for FlexFit.loose behavior
Real-world scenarios where Flexible is needed:
- Creating layouts where widgets should only take the space they need (loose fit)
- Building responsive designs that adapt to content size
- Implementing complex flex layouts that mix tight and loose fitting widgets
Current Limitation
// Currently impossible in RFW - only Expanded is available
Column(
children: [
Flexible( // ❌ Not supported
fit: "loose",
child: Text(text: "Only takes needed space")
),
Expanded( // ✅ Supported
child: Text(text: "Takes all remaining space")
),
],
)
Proposal
Add Flexible widget support to RFW's core widgets library with the following API:
flex: int (default: 1) - The flex factorfit: FlexFit enum ("loose" | "tight", default: "loose") - How the child fills available spacechild: Widget (required) - The widget below this in the tree
This matches Flutter's native Flexible widget API exactly, ensuring consistency and predictability for developers.
flutter/packages#9750 provides a complete implementation with tests.
