best way to keep token for login section in flutter-CodePudding

I wrote the registry system with http library in flutter and its database is mysql

I now want to write it login but I do not know what is the best way

For example, in React, we use Local Storage for storage data

but I do not know what is the best way to store token in the flutter

CodePudding user response：

Before use this add shared_preferences from https://pub.dev/packages/shared_preferences

Try this solution to store your token to local preference.

Save the data in shared-preference

SharedPreferences pref = await SharedPreferences.getInstance();
String token = '54dsfdsfsdfsdf5ad4f5sdafsd25f45';
pref.setString('token', token);

Retrive data from shared-preference

SharedPreferences pref = await SharedPreferences.getInstance();
String token = pref.getString('token')

CodePudding user response：

As mentioned by @Chirag,
shared_preference is a nice dependency to store data like user preferences.
But to store auth token or any other token I would prefer to use flutter_secure_storage so the token is encrypted and secured (it support all platforms)
