Hi guys i have an error in the flutter project that I cloned from GitHub. I tried this method but it didn't work

To :

<application
        android:name="${applicationName}"

can anyone help?

error:

AndroidManifest.xml:

CodePudding user response：

Add the following code in android manifest after activity

<meta-data
            android:name="flutterEmbedding"
            android:value="2" />

In project build.gradle add the following code in buildscript

ext.kotlin_version = '1.6.10'

And change gradle version in gradle-wrapper.properties

My manifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.stackoverflowexample">
   <application
        android:label="stackoverflowexample"
        android:name="${applicationName}"
        android:icon="@mipmap/ic_launcher">
        <activity

It may sound like a fake solution, but indeed, the easiest way to resolve this is:

Delete the android folder.
Run flutter create .

The command will recreate the android folder with the already migrated code. Also, the command will create folders for the other stable platforms (e.g. web, windows), so you could ignore those and just delete them or trigger the flutter create command by defining android - flutter create --platforms=android ..
