OptionalMethodChannel class Null safety

A MethodChannel that ignores missing platform plugins.

When invokeMethod fails to find the platform plugin, it returns null instead of throwing an exception.

All MethodChannels provided by the Flutter framework guarantee FIFO ordering. Applications can assume method calls sent via a built-in MethodChannel are received by the platform plugins in the same order as they're sent.
