Flutter error : Unresolved package dexterous

I am currently trying to use flutter local notifications.
To do this, we need to use flutter_local_notifications package.
I am unable to add it as a receiver in my Manifest.xml file and the error that keeps popping up is : Unresolved package dexterous.
Also, when I check my flutter plugins,
How can I resolve this?

I can't build or run my project

I tried to build and run my program. but I saw this message. what can I do?
Rishe is app name
Error 1 :
Error 2 :
Thanks in advance !

android.name is the class of your activity, not the application's name. Check the android developer's startup document.

error1 -> there is conflict coming with your app module manifest file with other module manifest file. see manifest merger tool http://tools.android.com/tech-docs/new-build-system/user-guide/manifest-merger or find how to merge mainifest file
error2 -> you are defining 3 activity with same name that is why it is giving error

android:targetPackage cannot resolve symbol

this might seem trivial but I can't understand why I'm getting this error.
I downloaded the sample app activityInstrumentation( from Android Studio File -> import Sample) and inside the testing project manifest I get an unresolved symbol for
android:targetPackage="com.example.android.activityinstrumentation".
After that I've created a manifest for my application and still there is an unresolved symbol on the attribute.
My application project dir and test project dir are:
app/src/main/java/com/example/appname
where manifest has
package="com.example.appname"
app/src/androidTest/java/com/example/appname
where manifest has
<manifest
...
package="com.example.appname.tests"
...
android:targetPackage="com.example.appname"
...
</manifest>
Please help me sort this out. I don't know what else I can do: using a sample app to create a full fledged test project was my very last hope.

You must specify android:targetPackage in instrumentation tag.

]

I see the same thing. Seems to be only false alert produced by the lint code inspection. When you run analysis (Analyze->Inspect code...) and open "Inspection" tab you can select the warning and mark it Suppress for tag. That will get rid of the warning.

android eclipse error creating google map

Got same problem. Check your manifest file. Activity name should be prefixed with a period ".".

Android Application class not found

In my application I use RoboGuice and the configuration for RoboGuice requires to add an Application-class and specify it in the AndroidManifest.xml file in the application-tag using the 'android:name' attribute.
So this is how my applicaiton-tag in the manifest looks like:
<application android:label="Worktime" android:icon="#drawable/logo" android:name=".guice.Application">
This always works and still does when I compile inside my IDE (IntelliJ) and deploy it to my device.
However when I want to run my tests using Ant (and only via Ant, this also still works in the IDE) I have this error on the console:
[exec] android.test.suitebuilder.TestSuiteBuilder$FailedToCreateTests:INSTRUMENTATION_RESULT: shortMsg=Unable to instantiate application eu.vranckaert.worktime.guice.Application: java.lang.ClassNotFoundException: eu.vranckaert.worktime.guice.Application in loader dalvik.system.PathClassLoader#44e88928
[exec] INSTRUMENTATION_RESULT: longMsg=java.lang.RuntimeException: Unable to instantiate application eu.vranckaert.worktime.guice.Application: java.lang.ClassNotFoundException: eu.vranckaert.worktime.guice.Application in loader dalvik.system.PathClassLoader#44e88928
This has worked before but started failing since I upgraded my 'Android SDK Tools' to revision 17 and the 'Android SDK Platform-tools' to revision 11.
Anyone who had this issue also or who knows how to fix it?

I think that the error saying
java.lang.ClassNotFoundException:
is occur only when you have create new class Activity and not declare(register) that in manifest file
please check if you have any new activity and not declare(register) that activity in manifest file
Thanks.

we might have encountered the same error - In my case the solution was to separate the Ant targets to two calls (i.e. "ant myParameters myTarget1 myTarget2", and "ant myParameters debug delivery"). Hope this works for you, anyhow - Google need to add better support for their undocumented/faulty changes (and stackoverflow isn't the best place for questions that are not originated in stupidity, as the lifetime of a complex question isn't too long here).
