大家好，我对Flutter还是新手，遇到了这个问题：
我的应用显然是V2版本，但是Android Studio仍提示需要迁移应用。
我按照建议执行了相应步骤，但结果依旧如此。 有谁可以告诉我我做错了什么吗？ 以下链接介绍了我需要做的内容： https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects
这是我修改过的文件：
AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.ipill">
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here. -->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.INTERNET" />

<application

<!-- Specifies an Android theme to apply to this Activity as soon as

android:resource="@style/NormalTheme"
/>
<!-- Displays an Android View that continues showing the launch screen
Drawable until Flutter paints its first frame, then this splash

gap between the end of Android's launch screen and the painting of
Flutter's first frame. -->
<!-- Specify that the launch screen should continue being displayed -->
<!-- until Flutter renders its first frame. -->
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<!-- Don't delete the meta-data below.

<meta-data
android:name="flutterEmbedding"
android:value="2" />
<meta-data
android:name="com.google.android.gms.wallet.api.enabled"
android:value="true" />
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value=""/>
</application>
</manifest>
文件 MainActivity.kt 包含以下内容：
package com.example.ipill
import io.flutter.embedding.android.FlutterActivity
class MainActivity: FlutterActivity() {
}
我尝试使用flutter install --ignore-deprecation命令，但他们说它无法工作。
需要帮助，因为我迷失了方向，我真的需要让应用程序工作。我找到了一个类似的问题，并尝试了他们建议的方法，但没有成功。
这是我得到的日志：
