SVG support would be very appreciated

I just wanted to note that there are also notifications on Android which only use `text` without any title! Therefore, it's displayed as > undefined: Message Text so maybe just...

I would like to vouch for the `manifest.json` file. We, for example, used it in our project and it is indeed different from the `pubspec.yaml` package name.

Wouldn't `retryIfResult` and `onRetryResult` be better names? "Value" seems a bit generic. Additionally, are there any plans on merging this PR?
