Why it must be use the await for save/get local data in Flutter?
I want to save data to local(just a few data), and I find several package for do that (e.g shared_preferences,secure_storage,sqflite), but all of them are need to use await (Future), if I use these, I have to change my existing codes for wrap in Future, but I just feel that's very troublesome, so I am wondering why all of these are need to use await for save data? or can I use another easy way to do that?
Thanks!

await as the name suggest wait for some event without stopping following lines of code to execute because that work will take some milliseconds to perform. So, it's a good idea to use await which needs to have async in the function.
There is other way of doing this work without using async-await.
That's then().
So, you go with this without having to add async to your function.
performWork().then((result) ));

To be clear: It is impossible to have a synchronous system call in flutter.
This is due to an architectural decision: Instead of having the language bridge, Flutter uses two bus (one dart, one native) sending messages to each other.
This is faster than by using a bridge but enforce asynchronous messages.

If you do not wish to use await you can call then() on the Future object. Refer this link for more details.
If you are working with Flutter you will definitely have to handle Future's there is no work around it.

If you do not wish to use await you can call then() on the Future object. Refer this link for more details.
If you are working with Flutter you will definitely have to handle Future's there is no work around it.
