[shared_preferences] Crash during use the SharedPreferences, when UserDefaults includes Date type object. #128948
Description
Is there an existing issue for this?
- I have searched the existing issues
- I have read the guide to filing a bug
Steps to reproduce
- Add into to UserDefaults record with type ‚Date’ eg:
Add in AppDelegate (in application method before ‚return’ statement)
UserDefaults.standard.set(Date.init(), forKey: "datatest1") - Add shared_preferences dependency into flutter app.
- Use SharedPreferences instance with access to all shared preferences.
SharedPreferences.setPrefix('');
await SharedPreferences.getInstance();
The issue?
iOS handle following data types in user preferences: NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary. See NSUserDefaults spec. If UserDefaults include Date type object, application will crash during reading preferences.
Following case can occur especially when migrating from a native app to flutter.
Expected results
App should be not crash.
Key (in user preferences) which included date object should include timestamp value.
Actual results
App crash:
