Support for Linux RISC-V #99963
Description
Activity
RISC-V now has experimental support in Dart, and is available for Linux SDKs from our beta channel: https://dart.dev/get-dart
Reacted by Maksim Lin, Caleb, Rocky, 12people, Kristijan Žic, Guy Luz, Francesco Iapicca, Nick, Graham Smith, Reid Baker and 3 moreGiven the slow CPU and low performance I've seen on the Allwinner D1 when running the Dart compiler, which at the moment is in the cheapest and most readily available development board, I think it would be most useful to start with supporting Linux on RISC-V using the same approach as Flutter has for mobile OS's (Android/iOS) as it would be a much better developer experience vs trying to do on-device development the way Flutter currently supports on Linux (and MacOS, Windows).

@maks Have a look at the StarFive VisionFive2 board which is more adequate for onboard development.
Thanks I do have the Vision five 2, but it's also too slow for reasonable on board development. Even a RPI4 is really too slow in terms of Dart compile times for decent DX when trying to do onboard development.

I support RISC-V for Engine and artifacts using Yocto, and have validated the Toyota custom embedder running flutter-gallery on a Deep Computing device. Layer and recipe located here:
https://github.com/meta-flutter/meta-flutter/tree/scarthgap/recipes-graphics/flutter-engineAside from the patches I have, it does require a newer version of the LLVM toolchain than what stable has. I believe it's one or two point releases beyond.
The recipe produces binaries and tools (dart/gen_snapshot) suitable for building and running AOT apps on the Linux GTK embedder.
Support was merged August 6th:

on Sep 18, 2025 Hello ! Given that almost a year has passed since the last comment on that issue, and that some recent commits are referencing it, is there any update ? Thank you :)

Use case
RISC-V is an upcoming CPU architecture which can similarly to ARM result in very energy-efficient processors. I won't start a discussion on benefits or issues related to RISC-V architecture; there are plenty out in the internet and in scientific environment.
Even though RISC-V is not very common for desktop or mobile devices yet, there is definitely momentum in the development RISC-V. Most major Linux and BSD distributions support RISC-V, such as Ubuntu, Debian or FreeBSD.
And what makes Linux all-day usable: Flutter of course. I would like to have this issue as a tracker for possibly upcoming RISC-V support and implementation.
Proposal
Flutter currently supports amd64 and aarch64 on Linux. I'd propose to add support for RISC-V in addition.
This should mainly consist of:
