Backdrop Modal Route

Get best of both worlds, backdrop with actual backdrop unlike material design and non sticky bottom sheet

This flutter package will help you create backdrop modal route or non sticky bottom sheet with minimal code and efforts with dynamic content.

• Android and IOS
• simple and easy
• no other dependencies
• well documented
• production-ready

This package was created as a need for our in-production app, as there is no single solution which gives you a route enabled bottom-sheet or backdrop which is route enabled and a new page with an actual backdrop unlike material design.

Getting Started

Add the dependency to your project and start using Backdrop Modal Route everywhere:

Import the package.

import 'package:backdrop_modal_route/backdrop_modal_route.dart';

Open backdrop with your custom widget which could be stateful/stateless.

// with custom return type T
final result = await Navigator.push(
      context,
      BackdropModalRoute<T>(
        overlayContentBuilder: (context) => 
            YourStatelessOrStatefulBackdropOverlayContentWidget(),
      ),
    );

Open backdrop with inline widget

// with inline widget
await Navigator.push(
      context,
      BackdropModalRoute<void>(
        overlayContentBuilder: (context) {
          return Container(
            alignment: Alignment.center,
            padding: const EdgeInsets.all(24),
            child: RaisedButton(
                onPressed: () => Navigator.pop(context),
                child: Text('Inline Close'),
            ),
          );
        },
      ),
    );

Creating custom block modal transitions

// ... more code
customBuildBlockModalTransitions:
    (context, animation, secondaryAnimation, child) {
    return RotationTransition(
        turns: animation,
        child: child,
    );
},
// ... more code
