Missing calls to "registerWith()" in generated dart_plugin_registrant.dart

[zr6328]

1. create a plugin by dartPluginClass
2. create a flutter project
3. compile the app by using cross-build's method
4. open the file .dart_tool/flutter_build/dart_plugin_registrant.dart
5. find the symbol of registerWith in libapp.so

In linux-x64,we can find the symbol of registerWith in libapp.so,but in linux-arm64,we can't find the symbol of registerWith in libapp.so

the plugin's pubspec.yaml look like this:

  plugin:
      implements: plugin_platform_template_interface
      platforms:
        macos:
          dartPluginClass: FlutterMacPlugin

the dart_plugin_registrant.dart look like this:

@pragma('vm:entry-point')
class _PluginRegistrant {
  @pragma('vm:entry-point')
  static void register() {
    print('zrzrzrzr register function called!!!!');
    if (Platform.isAndroid) {
      print("zrzrzrzr platform is android");
    } else if (Platform.isIOS) {
      print("zrzrzrzr platform is ios");
    } else if (Platform.isLinux) {
      print("zrzrzrzr platform is Linux");
      try {
        FlutterLinuxPlugin.registerWith();
      } catch (err) {
        print(
          '`flutter_linux_plugin` threw an error: $err. '
          'The app may not function as expected until you remove this plugin from pubspec.yaml'
        );
      }

    } else if (Platform.isMacOS) {
      print("zrzrzrzr platform is Macos");
      try {
        FlutterMacPlugin.registerWith();
      } catch (err) {
        print(
          '`flutter_mac_plugin` threw an error: $err. '
          'The app may not function as expected until you remove this plugin from pubspec.yaml'
        );
      }

    } else if (Platform.isWindows) {
      print('zrzrzrzr platform is Windows');
    }
  }
}

I believe this is not a bug of this software. Please see https://github.com/flutter/flutter/issues/113720. Thanks.

no, this method can't help me.

What version of flutter-elinux are you using? Also build commands.

[HidenoriMatsubayashi]

• what is the build target?

this is the build commands $ flutter build bundle --asset-dir=${RESULT_DIR}/${BUILD_MODE}/bundle/data/flutter_assets $ cp ${FLUTTER_SDK}/bin/cache/artifacts/engine/linux-x64/icudtl.dat \ ${RESULT_DIR}/${BUILD_MODE}/bundle/data/

Build kernel_snapshot.

• what is the build target?

Linux-x64 as the host, and Linux-arm64 as the target.

That is the official flutter tool. Did you try flutter-elinux instead of it? I recommend you to use flutter-elinux than manual commands with the flutter official tool.

ok, i will try it.

In flutter-elinux , i can also build the libapp.so?

[HidenoriMatsubayashi]

I'm not sure what you want to do, but you can build flutter apps with that tool. See Wiki.

[zr6328]

I'm not sure what you want to do, but you can build flutter apps with that tool. See Wiki. I want to build the libapp.so that can run i linux-arm64 in linux-x64 platform. Now, when I use the cross-build method, that can not run in linux-arm64.

When i run the command of flutter-elinux doctor, i can't find the /cache/artifacts/engine/linux-x64/icudtl.dat in the directory of bin

[HidenoriMatsubayashi]

You can build flutter apps with flutter-elinux and build artifacts can be found in under build directory. See https://github.com/sony/flutter-elinux/wiki/Building-flutter-apps

[HidenoriMatsubayashi]

If you use a target for normal Linux not elinux, please ask questions in flutter official repo.

I have clone the flutter-elinux, and run the flutter-elinux doctor, but In the bin's directory, i cant't find the directory of artifacts

[HidenoriMatsubayashi]

You should read Wiki in flutter-elinux before asking here.
