Setup channels during IntegrationTest registration on iOS #123729

jmagman · 2023-03-29T22:44:00Z

Allow iOS integration_tests to run from flutter drive and not just Xcode.

I wasn't able to get the originally reported stuck runloop from #48601 to reproduce, even when I totally reverted flutter/plugins#2465. I also validated flutter/plugins#2514 passes when it's reverted.

Talked to @gaaclarke and we suspect some precondition for the original bug have been resolved... somewhere. This code was moved from flutter/plugins to the SDK, making bisecting this tricky, and probably not worth it if I can't reproduce it from Xcode or the command line at all with either a static or dynamic linked integration_test. So let's try re-adding the +registerWithRegistrar channel setup removed in #48601.

Reverts flutter/plugins#2465 (not a clean revert but essentially the same thing).

Fixes #91668
Closes #116539

-+ (IntegrationTestPlugin *)instance;

+ (instancetype)instance;


Made this instancetype, that wasn't part of the revert.

+  FlutterMethodChannel *channel = [FlutterMethodChannel methodChannelWithName:kIntegrationTestPluginChannel

+  [registrar addMethodCallDelegate:[self instance] channel:channel];


For future archeologists: The addMethodCallDelegate does the setMethodCallHandler logic that was originally used, so this is semantically the same as the previous setMethodCallHandler call.

@pdblasi-google Hello, could you please tell me when do you expect this fix to be part of what future release?

pdblasi-google · 2023-04-17T16:56:22Z

@zubriktomas

From the release process docs this is already available in the master channel and may be in beta as well. I'm not personally sure when it'll be a part of a stable release, but it should be in either the next stable or the one after that.
