Flutter Secure Token Manager

What it does

• Secure Storage: Safely stores access token and refresh token.
• Efficient Token Refresh: Efficiently renews access tokens upon expiration, ensuring a single refresh request even when multiple requests detect token expiry simultaneously.
• Token Expiry Check: Provides a mechanism to check if tokens have expired (only for JWT).

Implementation Steps

1. Add Package: Include the package in your Flutter project.

   dependencies:
     flutter_secure_token_manager: ^latest_version
   

2. Set Tokens After Login: Use FlutterSecureTokenManager().setToken(Token(accessToken, refreshToken)) whenever there are changes to tokens.

3. Implement Token Expiry Check: If your tokens are not JWT, set the expiry check logic (usually done once at the beginning).

   FlutterSecureTokenManager().isTokenExpired = (accessToken) async {
     // Your logic here
     // return true or flase; //
   };
   

4. Token Refresh Logic: Implement the logic for refreshing the token when it expires.

   FlutterSecureTokenManager().onTokenExpired = (refreshToken) async {
      // Your logic here to get new access token with refreshToken;
      // return newToken;
   };
   

5. Access Token Retrieval: Use FlutterSecureTokenManager().getAccessToken() wherever you need the access token. The package will handle the refresh automatically.

   headers: {
     "Authorization": "Bearer ${await FlutterSecureTokenManager().getAccessToken()}"
   }
   

Note: Ensure these steps are appropriately integrated into your app flow, especially during the login process and before making authenticated requests.
