PR to pave the way for https://github.com/flutter/engine/pull/53001 to re-land Summary: - Enforces use of Kotlin >= `1.7.0` (please see below note) - Fixes ci failures that prevented the above PR from landing. Details: Because it landed initially, we are able to fake the roll in this PR to fix all the tests ([see my comment](https://github.com/flutter/flutter/pull/149204#discussion_r1617924772)). Fixes all the tests that failed: 1. `module_test` failing on multiple platforms (3/9 of the failures). Failure is ``` > Android resource linking failed ERROR:/b/s/w/ir/x/t/flutter_module_test.KECMXW/hello/.android/plugins_build_output/device_info/intermediates/merged_res/release/values/values.xml:194: AAPT: error: resource android:attr/lStar not found. ``` This is a rather unhelpful error message but some [folks online suggest](https://stackoverflow.com/a/69050529) that upgrading your `compileSdk` version fixes this. These resolve when I remove the dependency on the long discontinued [package_info](https://pub.dev/packages/package_info) and [device_info](https://pub.dev/packages/device_info) packages, perhaps because they are transitively pulling in low `compileSdk` versions? This is unclear to me. 2. `module_custom_host_app_name_test` was failing for the same reason (another 3/9, or cumulative 6/9). 3. `tool_integration_tests_3_4` was a flake ð (7/9) 4. `framework_tests_slow` needed a newer version of the Kotlin Gradle plugin (the flutter tool tells us this, so I just upgraded as suggested) and it resolved (8/9) 5.`android_preview_tool_integration_tests` needed newer AGP and KGP versions. I also refactored the tests, and bumped our error versions, fixing https://github.com/flutter/flutter/issues/142653. **Note that the bump to KGP is not in line with our policy** - we didn't warn for `1.5.0-1.6.x` for a release (or at all) before dropping support. But I think it might still be justified: - The bump to our androidx libraries unblocks ongoing Scribe work, and also includes a fix for a [memory leak](https://github.com/flutter/flutter/issues/129307#issuecomment-1601636959) and a [crash on folding phones](https://github.com/flutter/flutter/issues/114868#issuecomment-2133226962), among many other bug fixes. - Gradle [doesn't test on half of that range](https://docs.gradle.org/current/userguide/compatibility.html#kotlin), and so we implicitly can't claim to support it either. More generally, our Java and Kotlin support ranges should probably strictly fall within what Gradle tests.
Templates for Flutter Module
common
Written to root of Flutter application.
Adds Dart project files including pubspec.yaml.
android
library
Written to the .android/ hidden folder.
Contents wraps Flutter/Dart code as a Gradle project that defines an Android library.
Executing ./gradlew flutter:assembleDebug in that folder produces
a .aar archive.
Android host apps can set up a dependency to this project to consume Flutter views.
gradle
Written to .android/ or android/.
Mixin for adding Gradle boilerplate to Android projects.
host_app_common
Written to either .android/ or android/.
Contents define a single-Activity, single-View Android host app
with a dependency on the .android/Flutter library.
Executing ./gradlew app:assembleDebug in the target folder produces
an .apk archive.
Used with either android_host_ephemeral or android_host_editable.
host_app_ephemeral
Written to .android/ on top of android_host_common.
Combined contents define an ephemeral (hidden, auto-generated,
under Flutter tooling control) Android host app with a dependency on the
.android/Flutter library.
host_app_editable
Written to android/ on top of android_host_common.
Combined contents define an editable (visible, one-time generated,
under app author control) Android host app with a dependency on the
.android/Flutter library.
ios
library
Written to the .ios/Flutter hidden folder.
Contents wraps Flutter/Dart code for consumption by an Xcode project.
iOS host apps can set up a dependency to this contents to consume Flutter views.
host_app_ephemeral
Written to .ios/ outside the Flutter/ sub-folder.
Combined contents define an ephemeral (hidden, auto-generated,
under Flutter tooling control) iOS host app with a dependency on the
.ios/Flutter folder contents.
The host app does not make use of CocoaPods, and is therefore suitable only when the Flutter part declares no plugin dependencies.
host_app_ephemeral_cocoapods
Written to .ios/ on top of host_app_ephemeral.
Adds CocoaPods support.
Combined contents define an ephemeral host app suitable for when the Flutter part declares plugin dependencies.
