in my flutter android project, need to send serial request, so create a plugin to send serial request, contains below functions: 1, read excel config; 2, send serial request;
in root isolate, send serial port requests every 100ms to 200ms in a loop, so I create a child isolate;
but in child isolate, can not use the plugin, the plugin can only be instantiated in the child isolate;
so here is the question, in child isolate, during the plugin instantiation process, it will depend on Flutter Engine initialization. but in child isolate, the entryPoint must be a static function, can not dependent the Flutter Engine initialzation.
error log: I/flutter ( 2513): 协议备份失败:Binding has not yet been initialized. I/flutter ( 2513): The "instance" getter on the ServicesBinding binding mixin is only available once that binding has been initialized. I/flutter ( 2513): Typically, this is done by calling "WidgetsFlutterBinding.ensureInitialized()" or "runApp()" (the latter calls the former). Typically this call is done in the "void main()" method. The "ensureInitialized" method is idempotent; calling it multiple times is not harmful. After calling that method, the "instance" getter will return the binding. I/flutter ( 2513): In a test, one can call "TestWidgetsFlutterBinding.ensureInitialized()" as the first line in the test's "main()" method to initialize the binding. I/flutter ( 2513): If ServicesBinding is a custom binding mixin, there must also be a custom binding class, like WidgetsFlutterBinding, but that mixes in the selected binding, and that is the class that must be constructed before using the "instance" getter.
