sliver_glue.dart | 2.0.0

Helpers for easily mixing content in a Flutter CustomScrollView, simple as ListView & GridView.

Inspiration

sliver_glue exists mostly for mixing different kinds of content in a CustomScrollView. For a scrolling application, this is a possible common pattern in the same view.

• Header widgets / AppBar
• Grid of items
• A list of items

To use all of these in a CustomScrollView, using SliverList and SliverGrid have more boilerplate than using ListView and GridView.

sliver_glue aims to help with that problem, and goes a little beyond this too (providing dismissable-ness and dividing lines, common use-cases).

Getting Started

import 'package:flutter/material.dart';
import 'package:sliver_glue/sliver_glue.dart';

final List<String> text = ['A', 'B'];

class MyApp extends StatelessWidget {
  Widget _itemBuilder(BuildContext context, String str, _, __, ___) =>
    Text(data.text, key: Key(str));
 
  @override
  Widget build(BuildContext context) {
    return CustomScrollView(
      slivers: <Widget>[
        SliverGlueFixedList(
          widgets: <Widget>[
            Container(
              height: 200,
              child: Placeholder()
            )
          ],
        ),
        SliverGlueList(
          data: text,
          header: Text('Our List Header'),
          builder: _itemBuilder,
          divider: GlueDivider(enabled: true),
        ),
        SliverGlueGrid(
          data: text,
          builder: _itemBuilder,
          dismiss: GlueDismiss(enabled: true)
        )
      ],
    );
  }
}

void main() => runApp(MyApp());

MobX Integration

sliver_glue also provides widgets for MobX's ObservableList in the form of SliverGlueObservableList. To use this widget, import package:sliver_glue/mobx.dart.
