prism_adaptive_dialog

Adaptive dialogs for Flutter — modal bottom sheets on phones, centered dialogs on tablets and desktops, from a single call. The companion to prism_adaptive_scaffold. Pure Flutter — no platform channels, works on all six platforms.

Installation

dependencies:
  prism_adaptive_dialog: ^0.1.0

Usage

final confirmed = await PrismAdaptiveDialog.show<bool>(
  context,
  title: 'Delete item?',
  builder: (context) => const Text('This cannot be undone.'),
  actions: [
    AdaptiveDialogAction.cancel(context),
    AdaptiveDialogAction.destructive(
      context,
      label: 'Delete',
      onPressed: () => Navigator.pop(context, true),
    ),
  ],
);

On a 400px-wide phone this opens as a bottom sheet; on a 1200px desktop it opens as a centered dialog. Same code, correct UX everywhere.

Force a specific presentation

PrismAdaptiveDialog.show(
  context,
  presentation: PresentationStyle.dialog,     // always centered
  // presentation: PresentationStyle.bottomSheet, // always a sheet
  builder: (context) => const Text('Content'),
);

With prism_adaptive_scaffold

Breakpoints are shared, so dialogs inside PrismAdaptiveScaffold layouts automatically pick the right presentation for the current window class.
