I am using flutter_local_notification to send notifications. How do use Material Icons as Large icon in notifications.

I could use drawable resource as large icon, but I would have to create a vector asset for it, and I plan to use a large number of icons and creating one for each is not practical.

It doesn't seem possible. The largeIcon takes an AndroidBitmap which has a AndroidBitmapSource, which is one of three drawable filePath byteArray. Which is sent used to retrieve the image in the platform java code.

The only solution seems to be to add drawable resources you wished to avoid.

For changing notifications icon and sound you have to change icon in src folder of android module [android -> app -> src -> main -> res

also you can define notification text color in your src folder also in res -> values folder
