AndroidContentProvider class abstract

A communication interface with native Android ContentProvider https://developer.android.com/reference/android/content/ContentProvider

The native class is AndroidContentProvider.

Generally, this class should be used with extends and NOT implements, because it will remove a binding to the platofrm with a method channel.

However, implements could be used for:

  • using this class just as interface, or
  • for creating a custom native implementation by extending from AndroidContentProvider

The majority of the methods are called by the native platform to Dart. They can be overridden to implement some behavior.

But also, vice versa, some methods that are marked with native annotation are meant to be called from Dart to native. These methods will never be called from native to Dart.
