How to check user authorization in an application on Flutter?

Question

Mobile development

There is an application on flutter. There is a separate screen with an authorization form. From there, I retrieve the token and store it locally on the device. Tell me how best to check the relevance of the token on each screen?

For now, I'm thinking of using a provider and calling the token-checking method on each screen.
Maybe there is a better solution?

Answer 1

Well, you can use a singleton or a static method in the responsible class / function and call it to check.
