Web3Auth initialization and login code snippet below:
Initialisation:
Future<void> _initPlatformState() async {
final themeMap = HashMap<String, String>();
themeMap['primary'] = "#F5820D";
Uri redirectUrl;
if (Platform.isAndroid) {
redirectUrl = Uri.parse('w3a://com.example.app/auth');
} else if (Platform.isIOS) {
redirectUrl = Uri.parse('com.example.app://openlogin');
} else {
throw UnKnownException('Unknown platform');
}
final loginConfig = HashMap<String, LoginConfigItem>();
loginConfig['jwt'] = LoginConfigItem(
verifier: "toad-test-verifier", // get it from web3auth dashboard
typeOfLogin: TypeOfLogin.jwt,
name: "Custom JWT Login",
clientId: dotenv.env['WEB3AUTH_CLIENT_ID'],
);
await Web3AuthFlutter.init(
Web3AuthOptions(
clientId: dotenv.env['WEB3AUTH_CLIENT_ID'] ?? '',
network: Network.testnet,
redirectUrl: redirectUrl,
whiteLabel: WhiteLabelData(
dark: true,
name: "Toad Cash",
theme: themeMap,
),
loginConfig: loginConfig,
),
);
}
Login code:
VoidCallback _login(Future<Web3AuthResponse> Function() method) {
return () async {
context.showProgressBar();
try {
final Web3AuthResponse response = await method();
SharedPreference.setPrivateKey(response.privKey.toString());
SharedPreference.setIdToken(
response.userInfo?.idToken.toString() ?? '');
UserDetails userDetails = UserDetails(
name: response.userInfo?.name,
email: response.userInfo?.email,
profileImage: response.userInfo?.profileImage);
_proceedToSuccessScreen(userDetails);
} on UserCancelledException {
context.dismissProgressBar();
print("User cancelled.");
} on UnKnownException {
context.dismissProgressBar();
print("Unknown exception occurred");
}
};
}
Future<Web3AuthResponse> _googleSignInWithJWT() async {
var idToken = await _getFirebaseIdTokenFromGoogleSignIn();
return Web3AuthFlutter.login(
LoginParams(
loginProvider: Provider.jwt,
mfaLevel: MFALevel.NONE,
extraLoginOptions: ExtraLoginOptions(
id_token: idToken,
domain: 'https://toad.cash',
),
),
);
}
Future<String> _getFirebaseIdTokenFromGoogleSignIn() async {
var idToken = "";
try {
final GoogleSignInAccount? result = await GoogleSignIn().signIn();
final GoogleSignInAuthentication? googleAuth =
await result?.authentication;
final credential = GoogleAuthProvider.credential(
accessToken: googleAuth?.accessToken,
idToken: googleAuth?.idToken,
);
final userCredential =
await FirebaseAuth.instance.signInWithCredential(credential);
idToken = (await userCredential.user?.getIdToken(true)).toString();
} on FirebaseAuthException catch (e) {
if (e.code == 'user-not-found') {
print('No user found for that email.');
} else if (e.code == 'wrong-password') {
print('Wrong password provided for that user.');
}
}
return idToken;
}
_login(_googleSignInWithJWT) method called on Login button’s onPressed.
For iOS integration I have followed the steps mentioned here: https://web3auth.io/docs/sdk/pnp/flutter/install
