Re-sets two jvmargs that were getting cleared because we set a value for `-Xmx`. Could help with https://github.com/flutter/flutter/issues/142957. Copied from comment here https://github.com/flutter/flutter/issues/142957: >Two random things I ran into while looking into this that might help: > >1. Gradle has defaults for a couple of the jvmargs, and setting any one of them clears those defaults for the others (bug here https://github.com/gradle/gradle/issues/19750). This can cause the "Gradle daemon to consume more and more native memory until it crashes", though the bug typically has a different associated error. It seems worth it to re-set those defaults. >2. There is a property we can set that will give us a heap dump on OOM ([-XX:HeapDumpOnOutOfMemoryError](https://docs.oracle.com/javase/8/docs/technotes/guides/troubleshoot/clopts001.html)) Mostly just a find and replace from `find . -name gradle.properties -exec sed -i '' 's/\-Xmx4G/-Xmx4G\ \-XX:MaxMetaspaceSize=2G\ \-XX:+HeapDumpOnOutOfMemoryError/g' {} \;`, with the templates and the one test that writes from a string replaced by hand. I didn't set a value for `MaxMetaspaceSize` in the template files because I want to make sure this value doesn't cause problems in ci first (changes to the templates are essentially un-revertable for those who `flutter create` while the changes exist).
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.
