Flutter Foldable Support


Flutter Foldable Support is in public preview. Review the Modal routes PR and TwoPane widget PR on GitHub to provide feedback.

Flutter Foldable PR progress. MediaQuery is merged, while Dialogs and TwoPane are still pending review.

If you are interested only in MediaQuery support, you can consider switching to the Flutter master channel, using the flutter channel master command. If you also want to use TwoPane and dialogs, setting up requires using a custom version of Flutter.

  1. Clone the custom Flutter.
  2. Add the custom Flutter to your PATH.

These steps are explained in detail below.

Step 1. Clone the custom Flutter

Clone the repository of our Flutter Fork. The foldable_support_complete branch contains all the above PRs.

  1. git clone
  2. cd flutter
  3. git branch foldable_support_complete

Step 2. Add the custom Flutter to your PATH

Update your PATH to include the bin folder from the newly created folder from Step 1, according to your operating system: Windows | macOS | Linux | Chrome OS.

That's it! You now have a custom Flutter Framework fork on your machine that contain all the changes related to foldable support and are able to build your app using the new MediaQuery support, TwoPane widget and Hinge aware popup routes.
