Example
IconPicker use an internal MaterialIcon collection by default, but you can set your own icon collection.
You just need to pass in iconCollection param a Map<String, IconData>.
final Map<String, IconData> myIconCollection = {
'favorite': Icons.favorite,
'home': Icons.home,
'android': Icons.android,
'album': Icons.album,
'ac_unit': Icons.ac_unit,
...
}
IconPicker(
initialValue: 'favorite',
icon: Icon(Icons.apps),
labelText: "Icon",
title: "Select an icon",
cancelBtn: "CANCEL",
enableSearch: true,
searchHint: 'Search icon',
iconCollection: myIconCollection,
onChanged: (val) => print(val),
onSaved: (val) => print(val),
);
The result of val in onChanged, validator and onSaved will be a json String.
So, if you tap the icon ac_unit in the dialog window, the result value will be:
'{"iconName": "ac_unit", "codePoint": 60219, "fontFamily": "MaterialIcons"}'
Transforming the String result of IconPicker in an IconData:
String value = '{"iconName": "ac_unit", "codePoint": 60219, "fontFamily": "MaterialIcons"}'
var iconDataJson = jsonDecode(value);
IconData icon = IconData(iconDataJson['codePoint'], fontFamily: iconDataJson['fontFamily']);
Icon(icon);
