Describe the problem

1. Please consider linking some info on how far along it is for android and ios in terms of what situations migth want us to enable/disable, migration path,etc. (eg svgs)

2. It's a bit confusing that this is a situation build and run don't work the same, maybe highlight that

3. flutter run --help, didn't mention, maybe consider that

thank you
