By default, the app bundle contains your Dart code and the Flutter
runtime compiled for armeabi-v7a (ARM 32-bit), arm64-v8a
(ARM 64-bit), and x86-64 (x86 64-bit).

Test the app bundle

An app bundle can be tested in multiple ways—this section
describes two.

Offline using the bundle tool

If you haven’t done so already, download bundletool from the
GitHub repository.

Generate a set of APKs from your app bundle.

Deploy the APKs to connected devices.

Online using Google Play

Upload your bundle to Google Play to test it.
You can use the internal test track,
or the alpha or beta channels to test the bundle before
releasing it in production.

Follow these steps to upload your bundle
to the Play Store.
