Refresh Token In Flutter

I'm working on a finance project (Flutter) where the auth token gotten from the back-end expires frequently. How can I keep the token from expiring as long as the user is using the

Solution 1:

What I suggest is you can handle the things in simple manner like when fetching the data if the token expires you get a 401 unAuthorized Exception where you can ask for a new token(refresh Token) and then make the fetch request again. Let me know if it worked for you.

Solution 2:

Use oauth_dio: ^0.2.3 https://pub.dev/packages/oauth_dio

OAuthToken token = oauth.requestToken(
  RefreshTokenGrant(
    refreshToken: '<YOUR REFRESH TOKEN>'
  )
).then((token) {
    print(token.accessToken);
});
