Add a cli flag for toggling HCPP use, and enable it by gmackall · Pull Request #182516 · flutter/flutter

gmackall · 2026-02-18T00:26:54Z

Adds the flag (--enable-surface-control)
Adds a driver test which tests that we can upgrade all 3 of the create calls (HC, TLHC w VD fallback, TLHC w HC fallback)
Respects its use in create call

Does not yet rename it, will do that in a follow up as it's logically independent.

Code Review

This pull request introduces a new command-line flag, --enable-surface-control, to allow toggling the Hybrid Composition Platform Views (HCPP) feature on Android. The changes correctly plumb this flag from the Flutter tool down to the engine. A new integration test is also added, which effectively verifies that legacy platform view creation calls are upgraded to HCPP when the flag is enabled by checking logcat output.

My review found one area for improvement for the sake of consistency. In FlutterShellArgs.java, the default value for the new flag's intent extra is true, which is inconsistent with other similar flags like enable-impeller that default to false. I've suggested aligning this for better predictability.

+  void addEnableSurfaceControlFlag({required bool verboseHelp}) {
+    argParser.addFlag(
+      'enable-surface-control',
+      hide: !verboseHelp,


The flag name and its help text are meaningless to 99% of Flutter developers

very fair, am planning to rename it in an immediate follow up pr

    // Test HCPP Platform Views on Vulkan.
    if (impellerBackend == ImpellerBackend.vulkan) {
+      // Run upgrade_legacy_pv_types first, as it is testing the flag and not the manifest


nit can you put the full path here and explain why it matters that the test is testing the flag and not the manifest. It took me a bit to understand what upgrade_legacy_pv_types was referring to.

I would prefer not to add the full path, as there is no enforcement that it is correct. Someone might reasonably move the file up or down subdirectories, and the comment will become incorrect. Notably this is not true about the name in my opinion, because of the proximity of this comment to the check right below

-        // directory.
-        if (!file.path.contains('hcpp')) {
+        // directory, except for upgrade_legacy_pv_types which we already ran.
+        if (!file.path.contains('hcpp') || file.path.contains('upgrade_legacy_pv_types')) {


I think having the string helps with understandability but what do you think about having a list of runFirstTests and for now having it contain one item. I think it would make the callsite code easier to understand then the explanation for why a test needs to be run first can go adjacent to its entry in the list.

great comment

+          'got $legacyCount. Logcat:\n$logcat',
+    );
+  }, timeout: Timeout.none);


Is timeout none correct here?

Yeah, it's also the timeout used for all the other hcpp tests. It's only a per test timeout, so the target will still fail if it reaches the ci timeout
