logIn method
Logs in a user with a username and password. On success, this saves the session to disk, so you can retrieve the currently logged in user using currentUser.
Implementation
static Future<ParseUser> logIn(
{@required String username, @required String password}) async {
assert(username != null || username.isEmpty);
assert(password != null || password.isEmpty);
dynamic params = {'username': username, 'password': password};
return FlutterParse._channel
.invokeMethod('login', params)
.then((jsonString) {
return _parseResult(jsonString);
});
}
