I am developing a Bluetooth application using platform channel in flutter (using Java). But while I try to login with google-sign in( google_sign_in: ^4.5.6 ) I'm getting the error. I can login the details but I can't move to further page...... Actually, it's working in my office system, but when I copy the project and run in another it gives the error...Can anyone please help
main.dart
import 'package:bmsapp2/pages/loginpage.dart';
import 'package:flutter/material.dart';
void main() {
runApp(BmsApp());
}
class BmsApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
const curveHeight = 12.0;
return MaterialApp(
home: SafeArea(
child: Scaffold(
appBar: AppBar(
backgroundColor: Colors.amber[900],
shape: const MyShapeBorder(curveHeight),
),
body: LoginPage(),
),
),
);
}
}
class MyShapeBorder extends ContinuousRectangleBorder {
const MyShapeBorder(this.curveHeight);
final double curveHeight;
@override
Path getOuterPath(Rect rect, {TextDirection textDirection}) => Path()
..lineTo(0, rect.size.height)
..quadraticBezierTo(
rect.size.width / 2,
rect.size.height + curveHeight * 2,
rect.size.width,
rect.size.height,
)
..lineTo(rect.size.width, 0)
..close();
