Date: 2024-11-26

Status

Accepted

Context

• Flutter Service Worker have many issues regarding updating cache resources
  • https://github.com/flutter/flutter/issues/104509
  • https://github.com/flutter/flutter/issues/63500
• Flutter is moving away from Flutter Service Worker
  • https://github.com/flutter/flutter/issues/156910

Decision

• We remove the Flutter Service Worker and let the browser handle the cache by:
  • Remove the Flutter Service Worker initialization
  • Remove the existing Flutter Service Worker registration

Consequences

• Twake Mail web now will validate cache with the server every time it is loaded
  • If the status code is 200, new resources will be fetched
  • If the status code is 304, old resources will be used
• All of the existing service workers will be removed, even if it is not Flutter Service Worker
