Code Review

This pull request addresses an issue where popping a nameless route on the web did not preserve the URL of the previous named route. The fix involves introducing _currentRouteName to correctly track and restore the route name. The implementation is solid, simplifying the existing logic and adding a specific test case to validate the correction. The changes are well-executed and effectively resolve the bug.

LGTM, just some minor comment

engine/src/flutter/lib/web_ui/lib/src/engine/navigation/history.dart


    final String path = currentPath;
-    if (!_isFlutterEntry(domWindow.history.state)) {
+    _currentRouteName = path;


_currentRouteName = currentPath

engine/src/flutter/lib/web_ui/lib/src/engine/navigation/history.dart

  void setRouteName(String? routeName, {Object? state, bool replace = false}) {
    if (urlStrategy != null) {
-      _setupFlutterEntry(urlStrategy!, replace: true, path: routeName);
+      _currentRouteName = routeName ?? currentPath;


i think routeName will never be null given since routeUpdated method has been deprecated for ages.

Do you think it's safe to remove the entire routeUpdated handler:

flutter/engine/src/flutter/lib/web_ui/lib/src/engine/window.dart

Lines 628 to 632 in 1eb2f68

case 'routeUpdated': // deprecated

assert(arguments != null);

await _useSingleEntryBrowserHistory();

browserHistory.setRouteName(arguments!.tryString('routeName'));

return true;

yes, I think so, it has not been used since we have introduced Router. I forgot to clean it up

Ok, I'll do this cleanup in a follow up PR.

engine/src/flutter/lib/web_ui/test/engine/history_test.dart

      expect(spy.messages[0].methodArguments, '/page3');
      spy.messages.clear();
-      // 2. The framework sends a `routePushed` platform message.
+      // 2. The framework sends a `routeUpdated` platform message.


not something need to be address in this pr, routeUpdated is not used by framework for a long time now

engine/src/flutter/lib/web_ui/test/engine/history_test.dart

+      await implicitView.debugInitializeHistory(strategy, useSingle: true);
+
+      // Go to a named route.
+      await routeUpdated('/named-route');


let's use routeInformationUpdated for accuracy
