A Flutter app that depends on the plugin,
and illustrates how to use it.

By default, the plugin project uses Swift for iOS code and
Kotlin for Android code. If you prefer Objective-C or Java,
you can specify the iOS language using -i and the
Android language using -a. For example:

flutter create

=plugin

-platforms

=android,ios

i objc hello

flutter create

-template

=plugin

-platforms

=android,ios

a java hello
