flutter调用用kotlin编写自动生成检查并生成APP桌面快捷方式代码按照以上要求请提供完整代码以及导入包

由于具体需求和环境不清楚，下面是一个参考代码，仅供参考：

在Kotlin中实现自动生成检查并生成APP桌面快捷方式：

import android.content.Context
import android.content.Intent
import android.content.pm.PackageManager
import android.graphics.BitmapFactory
import android.os.Build
import androidx.annotation.NonNull
import androidx.annotation.RequiresApi
import androidx.core.content.ContextCompat
import androidx.core.content.pm.ShortcutInfoCompat
import androidx.core.content.pm.ShortcutManagerCompat
import androidx.core.graphics.drawable.IconCompat

fun createShortcut(context: Context, shortcutName: String, iconResource: Int, intent: Intent) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N_MR1) {
        createShortcutApi25(context, shortcutName, iconResource, intent)
    } else {
        createShortcutApi(context, shortcutName, iconResource, intent)
    }
}

@RequiresApi(Build.VERSION_CODES.N_MR1)
private fun createShortcutApi25(context: Context, shortcutName: String, iconResource: Int, intent: Intent) {
    val shortcutManager = context.getSystemService(ShortcutManager::class.java)
    if (shortcutManager.isRequestPinShortcutSupported) {
        val shortcutInfo = ShortcutInfo.Builder(context, shortcutName)
                .setShortLabel(shortcutName)
                .setIcon(IconCompat.createWithBitmap(BitmapFactory.decodeResource(context.resources, iconResource)))
                .setIntent(intent)
                .build()

        shortcutManager.requestPinShortcut(shortcutInfo, null)
    }
}

private fun createShortcutApi(context: Context, shortcutName: String, iconResource: Int, intent: Intent) {
    if (ShortcutManagerCompat.isRequestPinShortcutSupported(context)) {
        val shortcutInfo = ShortcutInfoCompat.Builder(context, shortcutName)
                .setShortLabel(shortcutName)
                .setIcon(IconCompat.createWithBitmap(BitmapFactory.decodeResource(context.resources, iconResource)))
                .setIntent(intent)
                .build()

        ShortcutManagerCompat.requestPinShortcut(context, shortcutInfo, null)
    }
}

fun isShortcutCreated(@NonNull context: Context, shortcutId: String): Boolean {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N_MR1) {
        return isShortcutCreatedApi25(context, shortcutId)
    } else {
        return isShortcutCreatedApi(context, shortcutId)
    }
}

@RequiresApi(Build.VERSION_CODES.N_MR1)
private fun isShortcutCreatedApi25(context: Context, shortcutId: String): Boolean {
    val shortcutManager = context.getSystemService(ShortcutManager::class.java)
    val shortcuts = shortcutManager.dynamicShortcuts
    for (shortcut in shortcuts) {
        if (shortcut.id == shortcutId) {
            return true
        }
    }
    return false
}

private fun isShortcutCreatedApi(context: Context, shortcutId: String): Boolean {
    if (ContextCompat.checkSelfPermission(context, "com.android.launcher.permission.READ_SETTINGS") != PackageManager.PERMISSION_GRANTED) {
        return false
    }

    val authority = "${context.packageName}.launcher.settings"
    val uri = Uri.parse("content://$authority/favorites?notify=true")
    val projection = arrayOf("_id", "title", "iconResource")
    val c = context.contentResolver.query(uri, projection, "title=?", arrayOf(shortcutId), null)

    if (c != null && c.moveToFirst()) {
        c.close()
        return true
    }

    return false
}

在Flutter中调用Kotlin代码：

在Flutter项目的android/app/src/main/kotlin目录下创建一个新的Kotlin文件，例如ShortcutUtil.kt。
在文件中添加上面的Kotlin代码。
在Flutter项目的pubspec.yaml文件中添加Kotlin依赖项：

dependencies:
  flutter:
    sdk: flutter
  kotlin:
    classpath: org.jetbrains.kotlin:kotlin-gradle-plugin:1.3.50

在Flutter项目的android/app/build.gradle文件中添加Kotlin插件和库依赖项：

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

在Flutter项目的android/app/src/main/AndroidManifest.xml文件中添加权限：

<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

在Flutter项目的Dart代码中调用Kotlin代码：

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:kotlin/kotlin.dart' as kotlin;

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      home: MyHomePage(),
    );
  }
}

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  static const platform = const MethodChannel('com.example.app/shortcut');

  Future<void> _createShortcut() async {
    try {
      await platform.invokeMethod('createShortcut', {
        'shortcutName': 'My App Shortcut',
        'iconResource': 'ic_launcher',
        'intent': {
          'action': 'android.intent.action.VIEW',
          'data': 'https://www.example.com',
        },
      });
    } on PlatformException catch (e) {
      print("Failed to create shortcut: ${e.message}");
    }
  }

  Future<void> _checkShortcut() async {
    bool isCreated = await kotlin.isShortcutCreated(context, 'My App Shortcut');
    print("Shortcut is created: $isCreated");
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Flutter Demo'),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Text(
              'Press the button to create a shortcut:',
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          _createShortcut();
          _checkShortcut();
        },
        tooltip: 'Create Shortcut',
        child: Icon(Icons.add),
      ),
    );
  }
}
