popup that will appear once with flutter-CodePudding

According to the information from the system, I want the user to see a popup when he first logs into the application.I want.Any ideas on how to do it?

For example, a person who completes a hospital appointment evaluates the service he received with a pop-up that will appear the next time he logs into the application.I want this popup to appear only once. The person went to the hospital, completed his appointment, this information came from the system, and the next time he entered, a popup appeared directly in front of him. This is the scenario

CodePudding user response：

You can use: https://pub.dev/packages/shared_preferences

When app is start then dialog is open you to save one boolean like isFirstTime == false

await prefs.setBool('newUser', isFirstTime);

When your is came again into the app, have to check in pref boolean is available or not

final bool? isFirstTime = prefs.getBool('newUser');

if(isFirstTime){
     openDialog();
}

if the value is false then will not show pop up
