checkAuthentication method
Checks the authentication status and performs actions depending on the status
If the User is not authenticated and ActiveGridAuthenticationOptions.autoAuthenticate is true this will call authenticate
If the token is expired it will refresh the token using the refresh token
Implementation
Future<void> checkAuthentication() async {
if (_token == null &&
options.authenticationOptions?.autoAuthenticate == true) {
await authenticate();
}
if (_token != null && _token?.expiresIn?.isNegative == true) {
// Token is expired refresh it
final client = await _client;
client.createCredential(refreshToken: _token?.refreshToken);
final authenticator =
testAuthenticator ?? Authenticator(client, urlLauncher: (_) {});
final credential = await authenticator.authorize();
_token = await credential?.getTokenResponse();
}
}
