checkSupport method

@override Future<bool> checkSupport()

Checks whether the current device and SIM card(s) support Firebase Phone Number Verification (PNV).

This is a lightweight, consent-free pre-check. Apps should call this before attempting getVerifiedPhoneNumber so that unsupported devices/carriers can fall back to a traditional SMS OTP flow (e.g. via firebase_auth) without ever showing the PNV consent sheet.

Implementation

@override
Future<bool> checkSupport() async {
  final supported = await methodChannel.invokeMethod<bool>('checkSupport');
  return supported ?? false;
}
