android - 我可以从 Dart 调用 Kotlin 函数吗

Question

使用 Flutter，可以通过类似以下方式调用 kotlin/swift 函数:

file.dart:

static const platform = const MethodChannel('my.test.flutterapp/battery');
final int result = await platform.invokeMethod('getBatteryLevel');

file.kt:

private val CHANNEL = "my.test.flutterapp/battery"
MethodChannel(flutterView, CHANNEL).setMethodCallHandler { call, result ->
          if (call.method == "getBatteryLevel") {
              ...
          } else {
              result.notImplemented()
          }
      }

是否有类似于从标准 Dart 应用调用 Kotlin 函数的东西，例如 Dart 控制台应用!

Plugin packages: A specialized Dart package which contain an API written in Dart code combined with a platform-specific implementation for Android (using Java or Kotlin), and/or for iOS (using ObjC or Swift). A concrete example is the battery plugin package.
