While building the iOS platform views support we only enabled it when the app developer explicitly specified it with a flag, the main reasons were using an untested thread configuration, and taking a performance hit (even when no platform view is used due to disabled raster cache). Now that we are using the same dynamic thread configuration whether platform views is used or not, and that raster cache works with platform views in the tree as well, we are almost ready to enabled the platform views support by default. As a first step, I'm enabling it for the Flutter Gallery app on which we run benchmarks. After monitoring the benchmarks and making sure the gallery takes no hit we should be more confident to enabled platform views by default. This change is expected to have no performance effect on the Gallery app at all.
Flutter Examples
This directory contains several examples of using Flutter. To run an example,
use flutter run inside that example's directory. See the getting started
guide to install the flutter tool.
For additional samples, see the
flutter/samples repo.
Available examples include:
-
Hello, world The hello world app is a minimal Flutter app that shows the text "hello, world."
-
Flutter gallery The flutter gallery app showcases Flutter's widgets, including its implementation of material design.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
-
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.dev/platform-channels/.
-
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.
Notes
Note on Gradle wrapper files in .gitignore:
Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
