[New] IconPackMode

You can now select the wished IconPack through the new argument: iconPackMode. This defaults to IconPack.material. For further usage have a look in the example.

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:

Call this to convert the picked IconData to a Map:

IconData to Map

  iconDataToMap(iconData)

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> {
  Icon _icon;

_pickIcon() async {
  IconData icon = await FlutterIconPicker.showIconPicker(context, iconPackMode: IconPack.cupertino);

  _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()
          )
        ])
      ),
    );
  }
