title: how to set dynamic icon for android react native firebase through http request
body: <p>Hi I am trying to set custom icon through http request.im using <a href="https://fcm.googleapis.com/fcm/send" rel="nofollow noreferrer">https://fcm.googleapis.com/fcm/send</a> api and trying to send notification and I have succeeded but the problem is I can't define custom icon.either it's not showing or it's showing default android icon. Also, it would be great if i can send base64 string as icon. My code is below: </p>
