Build grade failure after Flutter update

Build grade failure after Flutter update

I was getting this error after updateing dart and flutter project

android:exported needs to be explicitly specified for element 
<activity#androidx.test.core.app.InstrumentationActivityInvoker$EmptyFloatingActivity>. 
Apps targeting Android 12 and higher are required to specify an explicit value for android:exported 
when the corresponding component has an intent filter defined. 
See https://developer.android.com/guide/topics/manifest/activity-element#exported for details. 
FAILURE: Build failed with an exception.

After searching and trying many things, adding these other activities solved the problem:

        <activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$BootstrapActivity"
            android:exported="false" />
        <activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyActivity"
            android:exported="false" />
        <activity
            android:name="androidx.test.core.app.InstrumentationActivityInvoker$EmptyFloatingActivity"
            android:exported="false" />
