Flutter Network Errors: Fail Gracefully
Treat every network call as a promise that might break. In Flutter, catch exceptions at the HTTP boundary and map them to UI states like retry widgets. The footgun is letting Dio or http exceptions bubble up, crashing the app instead of degrading gracefully.
Treat every network call as a promise that might break, because mobile connectivity is a moving target. In Flutter, wrap your HTTP client in a repository that catches SocketException, TimeoutException, and 5xx codes, then maps them into sealed result classes. The UI should receive clear states like loading, offline, or retry rather than raw exceptions. The footgun is letting Dio or http exceptions propagate past the service boundary, crashing the app with a red screen or forcing ugly try-catch blocks inside widgets.
