The legacy fyne-cross⁠ container image for Docker Hub is a Docker image that contains a pre-configured environment for building and compiling Fyne⁠ based applications for cross-platform deployment. Fyne is an easy-to-use, modern, and lightweight Graphical User Interface toolkit that enables developers to create beautiful, responsive, and cross-platform desktop and mobile applications in Go programming language.

The fyne-cross container image includes all the necessary dependencies and toolchains required to build Fyne-based applications for various platforms, such as Windows, macOS, Linux, Android, iOS, and WebAssembly. This container image is particularly useful for developers who want to build and test their Fyne applications in a consistent and reproducible environment, without worrying about the complexities of setting up their local development environment.

The legacy fyne-cross container image is designed for Fyne v2.x and is based on Debian Buster. The last version of fyne-cross to use the legacy image is its version v1.3.
