How can I change App's Icon dynamically in Android and iOS Flutter

Question

I want to change my app's icon from inside app in Android and iOS. How can I achieve this to my app

I found this only package flutter_dynamic_icon on pub.dev to achieve this feature. — Ujjawal Maurya, Feb 17 '22 at 12:11

Its imposible to change app icons inside app. To change the application icon you need to configure it inside the android folder (manifest, drawable...) and in the ios folder. So when the application is built, it is stored and the icon is selected. It is not possible to change it without doing a new build.

You *can* change the app icon during the runtime between a set of different icons which you specify during the build. – luk2302 Feb 17 '22 at 12:07
How Google Calender do the same every day. Calender app changes its icon dynamically and shows current date in its icon. – Ujjawal Maurya Feb 17 '22 at 12:08
Please let us know how we can do the same – Ujjawal Maurya Feb 17 '22 at 12:08
@Maikzen I don't think that's correct, you can specify different icon for example for a different language of the device (i.e 1 icon for english 1 icon for w.e) – Dan Baruch Feb 17 '22 at 12:11

This flutter_dynamic_icon package can help. For me it worked on iOS

just add it flutter_dynamic_icon: ^2.0.0 to your project and do some changes accordingly

iOS configurations(I found only iOS): (If anyone found Android Configs please share with us)

Add icon images (here.png)

Add some lines in info.plist (>> Raw info.plist <<)

Dart code sample:

import 'package:flutter_dynamic_icon/flutter_dynamic_icon.dart';

try {
  if (await FlutterDynamicIcon.supportsAlternateIcons) {
    await FlutterDynamicIcon.setAlternateIconName("photos");
    print("App icon change successful");
    return;
  }
} on PlatformException {} catch (e) {}
print("Failed to change app icon");

...

// set batch number
try {
    await FlutterDynamicIcon.setApplicationIconBadgeNumber(9399);
} on PlatformException {} catch (e) {}

// gets currently set batch number
int batchNumber = FlutterDynamicIcon.getApplicationIconBadgeNumber();

Followed this exactly and it does not work – Luke Irvin Apr 09 '22 at 04:02
On which platform you are trying to achieve this. This only works on iOS as of now, Android support is yet to come – Ujjawal Maurya Apr 09 '22 at 06:23
iOS only at this moment. – Luke Irvin Apr 10 '22 at 21:10
What's the error showing up?? – Ujjawal Maurya Apr 11 '22 at 09:50
it always hits this - print("Failed to change app icon"); it's never successful in my simulator. – Luke Irvin Apr 11 '22 at 15:43
