I run my app in Android and suddenly this error comes related to build error and flutter_native_timezone I tried to update the version of kotlin and build but still it didnt work and it still gets error
Warning: Flutter support for your project's Android Gradle Plugin version (Android Gradle Plugin version 8.1.0) will soon be dropped. Please upgrade your Android Gradle Plugin version to a version of at least Android Gradle Plugin version 8.3.0 soon.
Alternatively, use the flag "--android-skip-build-dependency-validation" to bypass this check.
Potential fix: Your project's AGP version is typically defined in the plugins block of the `settings.gradle` file (/Users/rajpurohittanu/Documents/GitHub/generic-quiz-flutter/android/settings.gradle), by a plugin with the id of com.android.application.
If you don't see a plugins block, your project was likely created with an older template version. In this case it is most likely defined in the top-level build.gradle file (/Users/rajpurohittanu/Documents/GitHub/generic-quiz-flutter/android/build.gradle) by the following line in the dependencies block of the buildscript: "classpath 'com.android.tools.build:gradle:<version>'".
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring project ':flutter_native_timezone'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl.
> Namespace not specified. Specify a namespace in the module's build file. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.
If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.
* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.

# In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion.

The plugin flutter_native_timezone was last released four years ago. Since then, it has not been maintained.
Because of this, it is missing the change Gradle brought for adding a namespace attribute to the build.gradle file.
You have two choices here:
android {
namespace 'com.whelksoft.flutter_native_timezone' /// <----
compileSdkVersion 30
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
targetSdkVersion 30
minSdkVersion 16
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
lintOptions {
disable 'InvalidPackage'
}
}
Pay attention that there could also be other underlying issues.
