flutter -> kotlin 함수 호출

 

 

Flutter에서 코틀린 함수 호출..

 

in Flutter ->

 

static const platform = const MethodChannel('io.myapp.application');

 

함수 호출할때..

await platform.invokeMethod('getTestFunc');

 

getTestFunc부에 함수 이름 넣으면됨.

 

호출받는 MainActivity ...>

 

 

 

package com.project.application

import android.content.Context
import android.content.ContextWrapper
import android.content.Intent
import android.content.IntentFilter
import android.os.BatteryManager
import android.os.Build.VERSION
import android.os.Build.VERSION_CODES
import android.os.Bundle

// import io.flutter.app.FlutterActivity 는 더이상 사용되지 않는다고함
import io.flutter.embedding.android.FlutterActivity
// ---> 로 대체 하니 빌드가 됨...


import io.flutter.plugin.common.MethodChannel

import io.flutter.plugins.GeneratedPluginRegistrant
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.view.FlutterMain
import androidx.annotation.NonNull
import io.flutter.plugin.common.MethodChannel.Result
import io.flutter.plugin.common.MethodCall
import io.flutter.plugin.common.MethodChannel.MethodCallHandler;

 

 

class MainActivity: FlutterActivity() {
     private val CHANNEL = "com.project.application"

     override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
     super.configureFlutterEngine(flutterEngine)

     MethodChannel(flutterEngine.dartExecutor.binaryMessenger, CHANNEL).setMethodCallHandler {
     call, result ->
// Note: this method is invoked on the main thread.
// TODO

     when {
     call.method.equals("getTestFunc") -> {
     changeColor(call)
     }
       }
        }
}


private fun changeColor(call: MethodCall) {
println("111k")

}

공식문서대로 하니까 안됨..

이거보고 해결했다.
