[Discover + Join/Leave] Refresh Discover while keeping previous data
还没有人认领这个 Issue。
评估
调研方向
Start in lib/screens/discover_screen.dart, which depends on the Discover feed from #104 being in place, and use lib/screens/home_screen.dart as the reference for the existing loader and refresh pattern. Wrap the always-scrollable list in a RefreshIndicator, keep the current cards while the refresh is pending, and on failure keep them and show a short error. Done when flutter test test/screens/discover_screen_dp_d03_2_test.dart passes for the one-card-plus-failed-refresh case and flutter analyze is clean.

描述
What to build
Add pull-to-refresh to Discover without clearing the current list while loading. On failure, keep the previous meetings visible and show a retry message.
Files
lib/screens/discover_screen.dart(extend the prerequisite’s file)- Starting example: lib/screens/home_screen.dart
Steps
- Wrap a scrollable always-scrollable list in RefreshIndicator and reuse loader.
- On refresh keep previous cards while pending; replace on success.
- On failure retain previous cards plus short refresh error; finally stop indicator.
Example
Existing one card+failed refresh still shows one card and error; no realtime subscription.
Check it works
In test/screens/discover_screen_dp_d03_2_test.dart, check the example above and the failure or limit described in the steps. Run flutter test test/screens/discover_screen_dp_d03_2_test.dart and flutter analyze.
