pull_to_reveal #

A simple Flutter widget that wraps a ListView and selectively renders a hidden top element based on user scroll behavior.

Getting Started #

To use the PullToRevealListView widget in your Flutter project, you need only wrap it in a LayoutBuilder and then a Stack. These are excellent for adding a little life to a Scaffold background, or for programming a Pong client.

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

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

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      body: Center(
        child: PullToRevealTopItemList(
          itemCount: _counter,
          itemBuilder: (BuildContext context, int index) {
            return ListItemElement(index: index);
          revealableHeight: 50,
          revealableBuilder: (BuildContext context, RevealableToggler opener, RevealableToggler closer, BoxConstraints constraints) {
            return Row(
              children: <Widget>[
                SizedBox(width: 10),
                  child: TextFormField(
                    controller: searchController,
                    decoration: InputDecoration(
                      hintText: 'Search',
                      suffixIcon: Icon(Icons.search),
                  icon: Icon(Icons.cancel),
                  onPressed: () {
                    // Handles closing the `Revealable`
                    // Removes any filtering effects
                    searchController.text = '';
                    setState(() {
                      _filter = null;

[0.0.1-beta] - 2019-05-26

  • Creates PullToRevealListView widget that contains a hidden top widget users can pull to reveal. Forces iOS-style scroll physics across platforms to achieve this effect.

[0.0.1-beta-2] - 2019-05-28

  • Added dividerBuilder to place content between list and revealable

[0.0.1-beta-3] - 2019-05-29

  • Fixed issue where scroll behavior was different depending on whether or not ListView's content overflowed the visible area. Behavior is now different between those two scenarios, but both are acceptable. (When Revealed, and partially scrolling up: overflowing situations will finish closing the Revealable, whereas non-overflowing situations will revert back to a full reveal.) Before, non-overflowing situations reverted back to a full reveal, then blinked away. Very unsatisfying.

[0.0.1-beta-4] - 2019-06-01

  • Attribute consistency improvements (renamed topItemBuilder to revealableBuilder)
  • Improved close animation logic

[0.0.1-beta-5] - 2019-06-04

  • Added startedRevealed option for better user search discoverability

[0.0.1] - 2019-09-26

  • Fixed inconsistent scrolling/snapping behavior
  • Added [RevealableCompleter] flag for animation control
  • Significantly refactored of internal logic
  • Standardized example to filter on substrings instead of integers
