Allow skipping webOnlyInitializePlatform in Flutter for Web #40301

jonahwilliams · 2019-09-12T00:36:54Z

Description

Allow configuring whether webOnlyInitializePlatform is invoked by the shell automatically with the flag (--no)--web-initialize-platform to flutter run and build. Also fixes an issue with flutter build not checking for plugins.

cc @jacob314 PTAL and let me know if this is sufficient for your usecase

Also fixes #40389

Works like a charm! This will make my job incrementally porting from dart:html much easier!

jacob314 · 2019-09-12T05:17:06Z

packages/flutter_tools/lib/src/build_runner/build_script.dart

 import "${path.url.basename(buildStep.inputId.path)}" as entrypoint;

 Future<void> main() async {
  registerPlugins(webPluginRegistry);


doesn't matter for my use case but should this initialization line also be inside the if block?

I'll leave it out for now, plugins are still a WIP

jacob314 · 2019-09-12T05:19:15Z

packages/flutter_tools/lib/src/build_runner/build_script.dart


 Future<void> main() async {
-  await ui.webOnlyInitializePlatform();
+  if ($initializePlatform) {


doesn't really matter as it will be tree shaken anyway but you could write
${initializePlatform ? 'await ui.webOnlyInitializePlatform();' : ''}
to generate code with the initialize line omitted depending on the style you are going for with this generated code.

To simplify these case I'm going to leave it inline, I think we can revist later on

packages/flutter_tools/lib/src/build_runner/web_compilation_delegate.dart

      .childDirectory('.dart_tool')
      .createSync();
+    final FlutterProject flutterProject = FlutterProject.fromDirectory(projectDirectory);
+    final bool hasWebPlugins = findPlugins(flutterProject)


is this hasWebPlugins line an unrelated bug fix?

jacob314

lgtm once there is a test.

jonahwilliams · 2019-09-12T21:56:52Z

I'm going to change the command line flag name to be (--no)--web-initialize-platform

@jonahwilliams guess you can close #40389 with this.. Sorry for the noise.

jonahwilliams · 2019-09-12T22:04:41Z

@cbenhagen no problem!

jacob314 · 2019-09-12T22:32:06Z

packages/flutter_tools/lib/src/commands/build_web.dart

    usesTargetOption();
    usesPubOption();
    addBuildModeFlags();
+    argParser.addFlag('web-initialize-platform',


why prefix a flag to the web tool with web-? Seems less ambiguous in this case than the general case that this flag is only about initializing the web platform.

I want to keep the flag the same as what is provided as in run.dart. Since that is not web specific, I prefixed it.

packages/flutter_tools/test/general.shard/build_runner/build_script_test.dart

+
+    await builder.build(mockBuildStep);
+
+    verify(mockBuildStep.writeAsString(any, argThat(contains('if (false)')))).called(1);


nit: probably would be cleaner if your integration test could check for an
if (false) { initalizeWebOnlyPlatform(); }

jacob314

with a couple small nits. Thanks for implementing this so quickly!
