+This directory contains a partial snapshot of an old Flutter project; it is
+intended to replace the corresponding parts of a newly Flutter-created project
+to allow testing plugin builds with a legacy project.
+
+It was originally created with Flutter 2.0.6. In general the guidelines are:
+- Pieces here should be largely self-contained rather than portions of
+  major project components; for instance, it currently contains the entire
+  `android/` directory from a legacy project, rather than a subset of it
+  which would be combined with a subset of a new project's `android/`
+  directory. This is to avoid random breakage in the future due to
+  conflicts between those subsets. For instance, we could probably get
+  away with not including android/app/src/main/res for a while, and
+  instead layer in the versions from a new project, but then someday
+  if the resources were renamed, there would be dangling references to
+  the old resources in files that are included here.
+- Updates over time should be minimal. We don't expect that an unchanged
+  project will keep working forever, but this directory should simulate
+  a developer who has done the bare minimum to keep their project working
+  as they have updated Flutter.
+- Updates should be logged below.
+
+The reason for the hybrid model, rather than checking in a full legacy
+project, is to minimize unnecessary maintenance work. E.g., there's no
+need to manually keep Dart code updated for Flutter changes just to
+test legacy native Android build behaviors.
+
+## Manual changes to files
+
+The following are the changes relative to running:
+
+```bash
+flutter create -a java all_packages
+```
+
+and then deleting everything but `android/` from it:
+
+- Added license boilerplate.
+- Replaced `jcenter` in build.gradle with `mavenCentral`, due to the
+  jcenter.bintray.com shutdown.
+- Update `compileSdkVersion` from 30 to 33 to maintain compatibility
+  with plugins that use API 34.
+- Updates `gradle-wrapper.properties` from `6.7` to `6.7.1`, to add
+  support for the Kotlin gradle plugin. If a user runs into this
+  error, the error message is clear on how to upgrade.
+- Modifies `build.gradle` to upgrade the Android Gradle Plugin (AGP)
+  from version 4.1.0 to 7.0.0. If a user runs into an error with
+  the AGP version, the warning is clear on how to upgrade
+  the version to one that we support.
+- Modifies `gradle-wrapper.properties` to upgrade the Gradle version
+  from 6.7.1 to 7.0.2. If a user runs into an error with the Gradle
+  version, the warning is clear on how to upgrade the version to
+  one that we support.
