FlutterSimCountryCode.simCountryCode : "Reply already submitted" on Android

[silversquall]

Hello,

I'm using your FlutterSimCountryCode.simCountryCode API and despite the country code is well returned i'm getting the following (as if the call to android system was done twice).
Only tested with Android, will test later today with IOS

Env:
[√] Flutter (Channel dev, v1.5.3, on Microsoft Windows [Version 6.1.7601], locale fr-FR)
[√] Android toolchain - develop for Android devices (Android SDK version 28.0.3)

PS : the README is misleading
"Use getSimCountryCode() to get the country code"
--> should be FlutterSimCountryCode.simCountryCode instead.

thx !

Checking the 0.0.2 change logs: "Fixed Reply already submitted errors on Android."
But i'm still getting the same error with this version.

Tried to fix this again in 0.1.0. Please reopen if the issue stil occurs.
