Even if I start a new flutter project and just add cloud_firestore: ^3.2.0 in pubspec.yaml and I run I get FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ‘:cloud_firestore’.

com.android.builder.errors.EvalIssueException: defaultConfig contains custom BuildConfig fields, but the feature is disabled.
To enable the feature, add the following to your module-level build.gradle:
android.buildFeatures.buildConfig true

• 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.
Get more help at https://help.gradle.org.

BUILD FAILED in 8s
Error: Gradle task assembleDebug failed with exit code 1

when I put android.defaults.buildfeatures.buildconfig=true in gradle.properties I get this

FAILURE: Build failed with an exception.

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.
