Easy Search Bar

A Flutter plugin to help you handle search inside your application. Can be used inside appBar or inside your application body depending on your necessities.

Preview

Installation

In the pubspec.yaml of your flutter project, add the following dependency:

dependencies:
  ...
  easy_search_bar: ^2.5.0

Migrating from 1.x.x to 2.x.x

Now instead of using the EasySearchBar widget inside AppBar widget, you can replace the AppBar with it.

This is what you used before:

Scaffold(
  appBar: AppBar(
    title: EasySearchBar(
      title: 'Example',
      onSearch: (value) => setState(() => searchValue = value)
    )
  )
)

And this is what it is supposed to look like now:

Scaffold(
  appBar: EasySearchBar(
    title: Text('Example'),
    onSearch: (value) => setState(() => searchValue = value)
  )
)

Basic example with suggestions

You can create a simple searchbar example widget with suggestions with the following example:

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

void main() {
  runApp(const MyHomePage());
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String searchValue = '';
  final List<String> _suggestions = ['Afeganistan', 'Albania', 'Algeria', 'Australia', 'Brazil', 'German', 'Madagascar', 'Mozambique', 'Portugal', 'Zambia'];

  @override
  Widget build(BuildContext context) {
    return  MaterialApp(
      title: 'Example',
      theme: ThemeData(
        primarySwatch: Colors.orange
      ),
      home: Scaffold(
        appBar: EasySearchBar(
          title: const Text('Example'),
          onSearch: (value) => setState(() => searchValue = value),
          suggestions: _suggestions
        ),
        drawer: Drawer(
          child: ListView(
            padding: EdgeInsets.zero,
            children: [
              const DrawerHeader(
                decoration: BoxDecoration(
                  color: Colors.blue,
                ),
                child: Text('Drawer Header'),
              ),
              ListTile(
                title: const Text('Item 1'),
                onTap: () => Navigator.pop(context)
              ),
              ListTile(
                title: const Text('Item 2'),
                onTap: () => Navigator.pop(context)
              )
            ]
          )
        ),
        body: Center(
          child: Text('Value: $searchValue')
        )
      )
    );
  }
}

Note: If you want to create a FloatingAppBar and want the body content to go behind the AppBar you need to set extendBodyBehindAppBar Scaffold property to true. And it's also recommended to wrap your Scaffold inside a SafeArea.
