Dart/Flutter：应用程序在启动时崩溃

我已经尝试过几次升级flutter，但似乎也没有任何问题：

我最近换了笔记本电脑，并在这个新的笔记本上查看了我的代码的git存储库。有一些问题，但我最终解决了这些问题。唯一的区别是项目名称现在只是osszefogasaszanhuzokert，而包名称是osszefogasaszanhuzokert2-但我认为这不会造成任何问题。

我的猜测是，问题出在我的AndroidManifest.xml中的某个地方：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.zgyorkei.osszefogasaszanhuzokert2">

    <!-- The INTERNET permission is required for development. Specifically,
         flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->
    <uses-permission android:name="android.permission.INTERNET"/>

    <!-- 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. -->
    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="Összefogás A Szánhúzókért"
        android:icon="@mipmap/ic_launcher">
        <activity
            android:name="com.zgyorkei.osszefogasaszanhuzokert2.MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- This keeps the window background of the activity showing
                 until Flutter renders its first frame. It can be removed if
                 there is no splash screen (such as the default splash screen
                 defined in @style/LaunchTheme). -->
            <meta-data
                android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
                android:value="true" />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

我也有同样的问题。对我来说，这发生在我重命名我的应用程序和更改包名之后。我没有为Android正确地做这件事。

在遵循了这个如何更改包名的指南之后，对于Android来说一切都很好。

确保androidmanifest.xml和androidmanifest.xml和android/app/build.gradle和android/app/src/.../mainactivity.java中的包名称相同。还要检查iOS/runner/info.plistiOS版本cfbundlename的值。
