| 2 | How do you actually properly read and write different basic primitive data types, such as a String, an int, and a bool, using the shared_preferences package's own available methods? Flutter › Local Data Storage with SharedPreferences | Flutter | Local Data Storage with SharedPreferences | Beginner |
| 3 | How can you properly store a genuinely more complex object, such as a List of strings or a Map, using SharedPreferences, given that it only genuinely natively supports fairly simple basic primitive types directly?

| 4 | How does SharedPreferences actually genuinely work differently underneath on Android compared to iOS, in terms of exactly what genuine underlying native storage mechanism each platform actually respectively uses? Flutter › Local Data Storage with SharedPreferences | Flutter | Local Data Storage with SharedPreferences | Intermediate |
| 5 | Why should genuinely sensitive data, such as an authentication token or a password, never actually be stored using regular SharedPreferences, and what should genuinely be used instead?

| 6 | How can you properly and safely migrate existing data already stored using SharedPreferences over to a genuinely more full featured local database such as Hive, once an app's own particular storage needs have genuinely grown beyond what simple key value storage alone can reasonably handle?

| 14 | How can you let a user manually select and persist their own preferred theme, such as light, dark, or system default, rather than only relying on the device's automatic system setting? Flutter › App Theming & Dark Mode | Flutter | App Theming & Dark Mode | Intermediate |
| 15 | How does a background task's callback function actually run in a separate isolate, and what practical implications does this actually have for accessing shared app state or plugins from within that specific background task? Flutter › Flutter Background Tasks & WorkManager | Flutter | Flutter Background Tasks & WorkManager | Intermediate |
| 16 | How can a Flutter desktop app properly access the native operating system's own file system, such as letting a user open or save an actual local file, using the file_picker or similar dedicated packages? Flutter › Flutter for Desktop (Windows, macOS, Linux) | Flutter | Flutter for Desktop (Windows, macOS, Linux) | Intermediate |

| 18 | How should you properly design a message queuing and delivery confirmation system, ensuring a message genuinely sent while a WebSocket connection was temporarily disconnected is properly and reliably delivered once that particular connection actually genuinely reconnects?
