• SheetScaffold (title / header / body / actions at the end) is the body of every sheet fl_lib raises; PromptSheet stays as a typedef (TODO). showRowsSheet takes title, header and actions; a rows sheet with none lays out as before.
• No sheet over a sheet: showResizableSheet (so showRowsSheet too) raised from one is its next page; standalone: true is the way out.
• A context menu shown as a sheet: three plain entries or fewer are the sheet's buttons.
• Page switches: the height follows from the bottom, and a page that fills its room no longer opens at the previous page's cap first.
• On a desktop the sheet stands clear of the window's bottom and sides, every corner rounded; the surface is drawn by the page host from bottomSheetTheme.

Summary by CodeRabbit

• New Features

  • Added floating sheets on desktop, with consistent sizing, rounded corners, and improved page transitions.
  • Short context menus can now appear as button-style sheets; longer menus retain a row layout.
  • Sheets support separate titles, headers, and actions, with improved scrolling and keyboard navigation.
  • Resizable sheets can now open independently instead of stacking with the current sheet.

• Bug Fixes

  • Kept sheet headers and tag bars visible while choices scroll.
  • Improved loading and selectable-row layouts in pick sheets.

Walkthrough

The change introduces SheetScaffold for child and row sheets, updates context-menu and pick-sheet layouts, and adds standalone resizable sheets and floating desktop sheet surfaces. Tests cover scaffold layout, menu selection, pick-sheet states, and sheet-page behavior.

Changes: Sheet scaffold and entry points

Layer / File(s)	Summary
Shared scaffold and entry points lib/src/view/widget/sheet.dart, lib/src/core/ext/ctx/sheet.dart, test/sheet_scaffold_test.dart, test/sheet_test.dart, test/store_field_sheet_test.dart	SheetScaffold supports child and row bodies, optional headers and actions, and row focus traversal. Sheet entry points and lifecycle tests now use the scaffold.
Context menus and pick sheets lib/src/view/widget/context_menu.dart, lib/src/view/widget/pick_sheet.dart, lib/src/core/ext/ctx/sheet.dart, test/context_menu_sheet_test.dart, test/pick_sheet_test.dart, test/sheet_test.dart	Eligible short context menus use buttons; other menus use rows. Pick sheets use scaffold layouts for loading and choice states. Tag controls are outside the scrolling choices.
Resizable sheets and sheet pages lib/src/view/widget/resizable_sheet.dart, lib/src/view/widget/sheet_pages.dart, test/sheet_pages_test.dart	Resizable sheets can join an existing stack or use a standalone route. Desktop routes use bounded floating surfaces, and the pages host tracks page switches and animation completion.

Merge Risk: Low · previous review a4697

Short context-menu sheets can clip their lowest buttons on very short screens or at large text scales. On desktop, an app's themed sheet width is replaced by the new default width. Both are narrow edge cases with simple fixes and do not block the main workflows, so the PR is mergeable with follow-up.

Keep short-menu actions reachable when vertical space is limited.

On a short landscape screen or at a large text scale, three long action labels can make OverflowBar taller than the sheet. _showButtons supplies no scrolling body, and SheetScaffold places its actions directly in a non-scrolling Column. The lower buttons can be clipped; the former rows presentation could scroll to them. Make the actions scrollable when they exceed the available height, or use the rows presentation in that case. Flutter documents that OverflowBar changes to a column but does not provide vertical scrolling. (api.flutter.dev)

Preserve the theme’s sheet constraints.

If a desktop app sets bottomSheetTheme.constraints and the caller omits constraints, this fallback supplies a non-null route constraint. Flutter then ignores the theme constraint, so an existing custom sheet width changes to the new default. Use the theme constraint before applying the desktop fallback. (api.flutter.dev)
