I have a widget who should be shown on home screen after a number of app open events. I know I have to use shared preferences, but I don't know how to implement it.

CodePudding user response：

You can follow this setup

Here is Link: sharedpreferences

CodePudding user response：

int value = 0; // when app open event call get the int to check last time value value.

value = prefs.getInt("key") ?? 0 : prefs.getInt("key");

// when app open event call set the int with appended value.

SharedPreferences prefs = await SharedPreferences.getInstance(); prefs.setInt("key",(value 1));

// when you want to check that how many time app opens you can use this.

SharedPreferences prefs = await SharedPreferences.getInstance(); prefs.getInt("key");
