Linux support

[MuathAmer]

Is there an ETA for Linux support? And is there currently a workaround to running Monarch on Linux?

[fertrig]

There is no ETA yet. And, unfortunately, no workaround. However, we are setting up our infrastructure to scale our build process. This infrastructure work will make Linux builds easier for us.

We also have an alternative experience in mind which would make it easier to support Linux, and which we may extend to other platforms.

Also, we are hoping the Flutter team will start work on supporting multiple flutter desktop windows soon. That would be a good option for the Monarch Linux UX as well.

I'll leave this issue open to post updates and to gauge interest in Linux. Feel free to +1.

Hello. I have good news Waiting for the linux build...

[mjablecnik]

@fertrig So when do you will support Linux systems? Are any interesting news here? I would like to try Monarch in my Linux distro. :)

[fertrig]

The new Monarch architecture (released last week) will make it easier to add and maintain the Monarch Linux version. We are excited to leverage the new architecture for the Linux build.

We will prioritize our next chunk of work very soon. I'll post any Linux updates here. Stay tuned.

@mjablecnik : I landed up moving to https://www.widgetbook.io/ in the end, since I needed Linux support.

The nice thing about WidgetBook is that you also get web support for free, which many of my clients have quite loved, especially the designers when they want to quickly look at what a screen looks like.

Monarch now supports Linux! 🚀

We just merged the PR. We will update the website with setup instructions soon. In the meantime, if you would like to build Monarch yourself you can follow these steps:

• Install the Flutter Additional Linux requirements.
• Install sudo apt install lib32stdc++-12-dev.
• Build Monarch following these steps.

Enjoy!

Update: For now you have to build Monarch using the flutter master channel. We are waiting for this Flutter Engine PR to make it to the beta or stable channels.

When do you will provide your official build for Linux? Thank you

[fertrig]

@mjablecnik: I'm sorry. I forgot to mention that you have to use the flutter master channel. Monarch needs some Flutter Engine APIs which are not yet available on the stable or beta channels yet.

We are waiting for this Flutter Engine PR to make it to the beta or stable channel. Once that PR is in, I can provide Linux builds. Unfortunately, for now, you have to use flutter master channel.
