Support for 32-bit and 64-bit Android Bundles

From August 1st, 2019, Android apps that use native code and target Android 9 Pie will be required to provide a 64-bit version in addition to the 32-bit version when publishing to the Google Play Store. Since all Flutter apps include native code, this requirement will affect new Flutter apps submitted to the store, as well as updates to existing Flutter apps. This does not affect existing app versions published to the store.

This release includes support for building app bundles and APKs that support both 32-bit and 64-bit binaries, completing our work on https://github.com/flutter/flutter/issues/31922. By using this release when building an Android application, your App Bundle or APK now supports both 32-bit and 64-bit CPU architectures by default.
