#26303 added a template argument to invokeMethod, which triggers the strong_mode_implicit_dynamic_method analyzer warning in many call sites in the plugins repo.

We should add the type parameter to all these call sites, but we can only do that after bumping the Flutter dependency constraint which we will only do once the invokeMethod change makes it to the stable release.

For now we're suppressing the warning in all call sites (we're not disabling the lint wholesale as we still want it for the rest of the code)
