## 0.3.1
|
|
- New: `expanded` and `linearMainAxisAlignment` options for non-wrap layouts. When `expanded` is true, the group uses `MainAxisSize.max` and aligns items per `linearMainAxisAlignment` (or mapped from `alignment`). This enables internal center/right alignment without extra wrappers.
|
|
- Fix: Connected + menu overflow now consistently inserts a 2px gap before the overflow trigger (when `showDividers=false`) and uses a stricter width-fitting algorithm with a small epsilon to eliminate minor RenderFlex overflows.
|
|
- UX: Dropdown overflow popup is anchored bottom-right of the overflow button, has intrinsic width to fit its buttons, and aligns its internal buttons to the right.
|
|
|
|
## 0.3.0
|
|
- Breaking: Removed legacy `children` parameter. Use `actions: List<ButtonGroupM3EAction>` instead.
|
|
- Breaking: Renamed `groupSelection` API to `selection` for clarity.
|
|
- Added `ButtonGroupM3EAction` as the sole way to define buttons in a group.
|
|
- Added connected selection corner logic: only outer ends round; inner corners use token square radius; selected buttons fully round.
|
|
- Added 2px gap between connected buttons (when `showDividers=false`) and before overflow trigger.
|
|
- Added per-corner shape application via new `cornerRadiusOverride` in `ButtonM3E` to support mixed rounded/square corners in groups.
|
|
- Added new anchored dropdown overflow menu (default) using `overflowMenuStyle: ButtonGroupM3EOverflowMenuStyle.dropdown`; bottom sheet alternative retained (`bottomSheet`).
|
|
- Overflow trigger now rendered as a `ButtonM3E` for visual consistency.
|
|
- Improved overflow fitting algorithm (exact iterative width packing + epsilon) to eliminate minor RenderFlex pixel overflows.
|
|
- Added right-alignment support: maps `crossAxisAlignment` for linear layouts and allows popup buttons to align right.
|
|
- Misc: Refined measurement pass; popup menu intrinsic width matches widest action; dismissal on outside tap.
|
|

|
## 0.2.0
|
|
- New: Overflow handling options for non-wrapping groups via `overflow` parameter:
|
|
- `menu` (new default): show as many children as fit and place the rest in a bottom sheet opened by a trailing overflow icon.
|
|
- `scroll`: allow scrolling along the axis under bounded constraints.
|
|
- `none`: no special handling.
|
|
- Behavior: The default overflow changed from `scroll` to `menu` for a better UX in constrained layouts.
|
|
- Implementation: Converted `ButtonGroupM3E` to a StatefulWidget to measure child extents and avoid overflow.
|
|
- Tests: Added tests for scroll, wrap, vertical, and menu overflow scenarios.
|
|
|
|
## 0.1.2
|
|
- Prevent RenderFlex overflow in non-wrapping groups by auto-enabling scroll when axis constraints are bounded.
|
|
- Added widget tests covering horizontal/vertical bounded scenarios and wrap behavior.
|
|
|
|
