revoke method
Log out of Google. You must have set googleClientId
before calling this.
This revokes the access token and refresh token. It may take a second or so to take effect.
Implementation
Future<void> revoke() async {
await client.post(
Uri.parse(
'https://oauth2.googleapis.com/revoke',
),
body: {
'token': _accessCredentials.accessToken.data,
},
);
}
