How to get Firebase UID knowing email user?

由 霸气de小男生 提交于 2021-02-11 13:17:35
问题 I am building a Flutter app where the administrator profile can create users to access their company. The code works right, unless the new user was previously created for another company. In this case an error of type ERROR_EMAIL_ALREADY_IN_USE appears from FIREBASE AUTH. What I want to do is simply retrieve the assigned UID from FIREBASE AUTH, which is necessary to assign the user within my database to an additional company. It's my code... _register(LoginBloc bloc, BuildContext context)

Stop pre-installed screen recording apps from recording screen in android

由 十年热恋 提交于 2021-02-11 12:48:58
问题 I am using flutter and have disabled normal apps from recording the screen. Here is the code getWindow().setFlags(WindowManager.LayoutParams.FLAG_SECURE, WindowManager.LayoutParams.FLAG_SECURE); The problem is there are some phones where screen recordings apps are pre-installed and above code can't stop them from recording the screen. So is there any other way to stop these apps from recording the screen? On other answers I saw that this was not possible but there are some apps on playstore
