Question

I'm new in flutter so please don't kill me if my question is easy.

notification icon doesn't show like this

I put in this path

\android\app\src\main\res\drawable

here is my code for icon:

 final settingsAndroid = AndroidInitializationSettings('app_icon');
 final settingsIOS = IOSInitializationSettings(onDidReceiveLocalNotification: (id, title, body, payload) => onSelectNotification(payload));
 final settingsIOSgeneral = IOSInitializationSettings(onDidReceiveLocalNotification: (id, title, body, payload) => onSelectNotificationgeneral(payload));
 notifications.initialize(InitializationSettings(settingsAndroid, settingsIOS), onSelectNotification: onSelectNotification);

Can Any one help me please how can I preview my icon in notification ?

Answer 1

I did the following and it worked for me:

1. Create a transparent and white notification icon (you can use the following tool: AndroidAssetStudio )

Download the zip folder, unzip and you'll see it contains a res folder with different drawable folders. Copy and paste the contents of the res folder in "android\app\src\main\res" path

2. Then open the AndroidManifest.xml file and add the following lines to it:

ic_stat_calendar_today is the name of my notification icon. And each of the drawable folders that have been pasted contain a different size of icon with the same name.

3. If you want to change the color of the icon then check the above image. Add the metadata tag after the notification icon tag

4. Go to "android\app\src\main\res\values" and add a colors.xml file

<color name="colorAccent">#00FF00</color>

This could be because the icon image is not transparent -- Try the notification icon generated from this tool. Also check this question Android Push Notifications: Icon not displaying in notification, white square shown instead
