Learn more about shared_preferences → goo.gle/3LJQITK
Your app runs everywhere and you want to save some simple data, but persistent storage requires platform-specific code … shared_preferences abstracts away all of the platform-specific code for accessing persistent storage so that you can write your code once and have it work across platforms.
This video is also subtitled in Chinese, Indonesian, Italian, Japanese, Korean, Portuguese, Spanish, Arabic, and Vietnamese.

This is the first plugin i looked for when i started learning flutter

Why do i see this just now after 3 months of programming haha

@Rick-ng3lr 2 года назад

I didn’t know there’s no guaranteed write with shared_preferences. Good to know. Thx!

@HarveyJoness Год назад

well, it is up to the condition of the storage of your device.

@dllizheng Год назад

@@HarveyJoness what does that mean?

@HarveyJoness Год назад

@@dllizheng If your storage is full or not working properly for any reason it's not guaranteed to save your data as it is told in the video.

@dllizheng Год назад

@@HarveyJoness Doesn't it return an error or throw some exception when saving?

@HarveyJoness Год назад

@@dllizheng Yes it does. But If your storage is broken someway after you saved your data succesfully, there is no chance to save your data back. And obviously no chance to throw an exception.

Flutter dev.. please look into the device default fonts to be used instead of the Flutter default. It is very important. Make the Flutter apps to adapt to the selected default fonts on the device.

@keidev7717 2 года назад

flutter is already implemented this by default

@luchitv1 2 года назад

@@keidev7717 no it doesn't work. The app uses default font of flutter instead of the device selected fonts

@mohamedayman5240 Год назад

whats the problem with that .. u will use your custom fonts anyway

This a package of decade))

@MehediHasan-co5qz 2 года назад

Love you Flutter❤️❤️❤️

@crazy-man 2 года назад

also a good package, but get_storage package is more convenient, only I use it now because I don’t need to use async

@SethuSenthil 2 года назад

This is so true. It often times makes life so much easier too, no need for unnecessary future builders for reading simple values from the disk. Wish I knew this before!

@biigsmokee Год назад

Do not use getx-based packages, they are bad

@hydernotes 6 месяцев назад

I'm getting.init() error in get storage. I'm thinking to revert back to the shared preferences.

@umitkirtil 2 года назад

Auth tokens ? Is it a bad practice to save user token to shared pteferences ?

@desther 2 года назад

It would be better IMO to use flutter_secure_storage for this usecase.

@@desther thnk you very much. i will look into it

@raglandasir6885 2 года назад

If Flutter uses local storage for the web to store shared_preferences, then it could be a problem

@umitkirtil 2 года назад

@@raglandasir6885 hi i use flutter for mobile only. but flutter_secure_storage looks more useful

For unknown reason, on some iPhone, the shared preference doesn't work We tried on two same model of iPhone with the same OS version, but on one it works like a charm but not on the other one

Is there something to save files in the local storage? Like songs in music directory on Android. Or just saving in Download dir.

Hello Michael, we'd recommend checking out the following guide for the shared_preferences Package of the Week: goo.gle/3yWIowo

not DataStore in Android???

Already using.

If this is not reliable then what to use for critical info storage?

@noahderebe 2 года назад

sqflite and other persistent storage methods.

@richardjecooke8036 2 года назад

So how do we store data across devices in local storage, where we *can* rely on it being written to disk?

@Abdullah-vp2tl 2 года назад

You can use dart:io library but it doesn't support web applications

@richardjecooke8036 2 года назад

@@Abdullah-vp2tl Yeah, there's no way of doing it, I looked at all packages. And then I realised a PWA works on web, mobile, and desktop, so I gave up on Flutter and went back to advanced web dev.

@yaqub3567 2 года назад

So never ever try to save widgets state with this package

@michasengotta2295 2 года назад

No they meant "persisted", because preferences may also be stored in temporary memory, for instance if a user uses the incognito mode in their browser.
