[dart2js] Static JS interop using @staticInterop problem #48244
Description
Problem
BluetoothUUID has several static methods. I tried several JS interop and all failed
@js('BluetoothUUID') on class
@JS('BluetoothUUID')
class BlueUUID {
external static Object getService(String name);
}: Error: Non-static JS interop class 'BlueUUID' conflicts with natively supported class '_BluetoothUUID' in 'dart:html'.
Try replacing it with a static JS interop class using `@staticInterop` with extension methods, or use js_util to interact with the native object of type '_BluetoothUUID'.
class BlueUUID {
@js('BluetoothUUID.getService') on class method
@JS()
class BlueUUID {
@JS('BluetoothUUID.getService')
external static Object getService(String name);
}Unhandled exception:
Unsupported operation: static members do not support "." in their names. See https://github.com/dart-lang/sdk/issues/27926
