I wonder if the Flutter engine would work on a Linux system that has only 128MB or 256MB? I've been playing around with devices like this https://www.ebay.com.

I wonder if the Flutter engine would work on a Linux system that has only 128MB or 256MB? I've been playing around with devices like this https://www.ebay.com.au/itm/WiFi-Display-Dongle-1080P-Wireless-Mini-TV-Receiver-HDMI-Miracast-DLNA-Airplay/323786315234 https://www.ebay.com.au/itm/WiFi-Display-Dongle-1080P-Wirele... and it would be fun to run Flutter engine on them. edit - would also be fun on the 4GB RAM rk3399 http://rockchip.wikidot.com/rk3399 http://rockchip.wikidot.com/rk3399 tv box: https://www.ebay.com.au/itm/X99-TV-BOX-4K-UHD-RK3399-4GB-32GB-ROM-Android-7-1-2-4G-5G-WIFI-64Bit-BT4-1-Media/293007973727 https://www.ebay.com.au/itm/X99-TV-BOX-4K-UHD-RK3399-4GB-32G... open source LInux support is here: https://github.com/rockchip-linux https://github.com/rockchip-linux

Interesting device. I think RAM shouldn't be the bottle neck, but CPU/GPU speed and memory might be. Do you already know how to get your own software on there?

  rk3036 with dual core ARM and Mali 400 GPU http://rockchip.wikidot.com/rk3036 http://rockchip.wikidot.com/rk3036 You use buildroot to get your own software on it. CPU: Dual-core ARM Cortex-A7 128KByte unified L2 Cache GPU ARM Mali400 High performance OpenGL ES1.1 and 2.0, OpenVG1.1 etc Embedded 1 shader core with shared hierarchical tiler Memory Video Real-time video decoder of MPEG-1, MPEG-2, MPEG-4,H.263, H.264, VP8, MVC

That Rockchip has an ancient Mali 400 GPU (with no open source drivers) that won't be able to render a Flutter app at 1080p, or lower even. The engine library alone is also already ~70 MiB. Running the Flutter Demo on my RPi3 (in aarch64, so the numbers are somewhat inflated) it's at 250 MiB of memory (with about 60 MiB of that for the system) and an additional 60 MiB of graphics memory. This is on a 1366x768, where the RPi graphics just about manage 60 fps (when warmed up).

  So it does not sound encouraging for Flutter on $20 HDMI sticks.

    We have $80 retail smartphones that blow this chip out of the water, so I have no doubts you can make a very good performing $20 Flutter stick. It's just that currently, it takes about 10 years for any sort of mobile throwaway hardware to get some sort of open source support that would make this possible for the home tinkerer.

      Rockchip - the maker of the rk3036 CPU are pretty good with their open source: https://github.com/rockchip-linux https://github.com/rockchip-linux >>We have $80 retail smartphones that blow this chip out of the water I'm interested in things that plug in to HDMI. This for example is $150 https://www.ebay.com.au/itm/X99-TV-BOX-4K-UHD-RK3399-4GB-32GB-ROM-Android-7-1-2-4G-5G-WIFI-64Bit-BT4-1-Media/293007973727 https://www.ebay.com.au/itm/X99-TV-BOX-4K-UHD-RK3399-4GB-32G... and uses the newer rk3399 chip http://rockchip.wikidot.com/rk3399 http://rockchip.wikidot.com/rk3399
