Yesterday, the RustDesk project officially merged the flutter_desktop branch into the master branch in preparation for the final release.
The first desktop version of RustDesk used Sciter. The primary reason for choosing Sciter was its light weight, but Sciter is not open source. The author of Sciter launched an open source Kickstarter last year, but it failed.
We decided to migrate in this May, and hosted an discussion about chosing Flutter or Tauri, https://github.com/rustdesk/rustdesk/discussions/533.
Now RustDesk fully embraces Flutter, Flutter is adopted on all platforms (iOS / Android / Windows / Linux / Mac / Web). But since Flutter does not support 32bit Windows, Sciter still has to continue to serve for 32bit Windows.
