You’ll learn how to customize the push notification icon launched in React Native with the @react-native-firebase/messaging library today.

We’ll go to app.json:
"notification": { "icon": "./src/assets/notification-icon.png", "color": "#d76d6d" },
We also added to the config plugin:
"@react-native-firebase/messaging"
With this, we’re halfway done.
Now we need to create our notification icon.
Only applies to Android.
The icon must be:
Size: 96 x 96
Color: white
Format: .png transparent
We save it in the indicated path within the assets.
Now we execute this command:
npm run prebuild
This is how our icon will be generated.
