    Check flutter doctor status. The issue likely is in the java bundle.

    tl;dr Update Android Studio and Gradle Versions

    I encountered this error while trying to run Flutter integration tests on Firebase Test Lab. I was able to solve this by updating a few things in Android Studio.

    Update the Project’s JDK

    1. Open the Android Studio Project Structure page (File -> Project Structure)

    2. Click the "SDKs" tab

    3. Download the newest JDK version and add it to the list

    4. Click the "Project" tab

    5. Update the SDK field to the new JDK

    Update com.android.tools.build:gradle

    In android/build.gradle, update the com.android.tools.build:gradle value to the latest version found here.

     dependencies {
        classpath 'com.android.tools.build:gradle:7.4.1'
        ...
    }

    Update the gradle distributionUrl

    In android/gradle/wrapper/gradle-wrapper.properties, update the distributionUrl property to use the latest Gradle version.

    distributionUrl=https://services.gradle.org/distributions/gradle-7.6-all.zip
