Android embedding API updates for plugin ecosystem #13280

matthew-carroll · 2019-10-22T05:43:02Z

FlutterPluginBinding is a facade, getFlutterEngine() is deprecated
Lifecycle is split between ActivityAware and ServiceAware, FlutterEngine#getLifecycle() is deprecated
Activity instance state saving callbacks are forwarded to plugins

…gine, split Lifecycle across ActivityAware and ServiceAware and deprected getLifecycle().

@amirh @mklim @cyanglaz @bparrishMines @collinjackson @kroikie Can you all please take a look at FlutterPluginBinding and let me know if you have any thoughts about additions/removals of accessors as a facade for plugins? I went with the few things that seemed obvious and necessary. We should try to reach consensus on that API surface ASAP. Thanks.

mklim · 2019-10-24T00:10:31Z

The facade API LG to me, I didn't notice anything missing. I could very likely be forgetting an edge case though.

tvolkert · 2019-10-24T01:32:19Z

API LGTM. We can always add more to the surface if needed later.

collinjackson

lgtm from a testing and Flutterfire perspective.

…saving callbacks are forwarded to plugins.

matthew-carroll · 2019-10-24T04:41:00Z

I added JVM tests to ensure that the new plugin facade references are not null when the binding is given to plugins. I also verified that state saving callbacks are forwarded to plugins that register for them.

matthew-carroll · 2019-10-24T21:47:20Z

@mklim would you mind taking a look at this PR? I'd like to merge this in before beginning work on creating a custom Lifecycle interface.

mklim

LGTM

getFlutterShellArgs() is non-nullable, right?

readability nit: It would probably be better to create a stub than a mock here. Subjective but stubs are generally easier to reason about than a series of when...thenReturn() statements.

Sure. I switched out those mocks for fake implementations.

kroikie · 2019-10-24T22:09:02Z

LGTM from FlutterFire end.

Lifecycle should be fetched through the flutter_android_lifecycle plugin, and not available directly here
