FlutterIconPicker

This package provides an IconPicker with all Material Icons which can be picked through an AlertDialog. All Icons are mapped with its names in the IconData. This is necessary to make it possible to search through the icons. Fulltextsearch including a note if no results where found.
FlutterIconPicker

Usage

To use this package, add flutter_iconpicker as a dependency in your pubspec.yaml file.

Result of IconPicker and further usage (saving and retreiving)

The picker is returning (as shown in the example method _pickIcon() underneeth) an IconData which is nothing else then this class for example:

  IconData(0xe3af, fontFamily: 'MaterialIcons');    // Icons.camera

that's representing an Material icon.

So if you plan to save the picked icon anywhere (sqflite, firebase, etc.), you can use the serialization methods:

  1. Import:
  import 'package:flutter_iconpicker/Serialization/iconDataSerialization.dart';
  1. Call this to convert the picked IconData to a Map:

IconData to Map

  iconDataToMap(iconData)
  1. You can retreive the IconData by passing the mapped IconData:

Map to IconData

  mapToIconData(map)

Example

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

void main() {
  runApp(MaterialApp(
    home: HomeScreen()
  ));
}

class HomeScreen extends StatefulWidget {
  HomeScreen({Key key}) : super(key: key);

  @override
  _HomeScreenState createState() => _HomeScreenState();
}

class _HomeScreenState extends State<HomeScreen> {
  Widget _icon;
  
_pickIcon() async {
  IconData icon = await FlutterIconPicker.showIconPicker(context,
    iconSize: 40,
    iconPickerShape:
        RoundedRectangleBorder(borderRadius: BorderRadius.circular(15)),
    title: Text('Pick an icon',
        style: TextStyle(fontWeight: FontWeight.bold)),
    closeChild: Text(
        'Close',
        textScaleFactor: 1.25,
    ),
    searchHintText: 'Search icon...',
    noResultsText: 'No results for:'
  );
  
  _icon = Icon(icon);
  setState((){});
  
  debugPrint('Picked Icon:  $icon');
}
  
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        crossAxisAlignment: CrossAxisAlignment.center,
        children: <Widget>[
          RaisedButton(
            onPressed: _pickIcon,
            child: Text('Open IconPicker'),
          ),
          SizedBox(height: 10),
          AnimatedSwitcher(
            duration: Duration(milliseconds: 300),
            child: _icon != null ? _icon : Container()
          )
        ])
      ),
    );
  }
}
