Describe the bug
Currently, the boot_screen in pyproject.toml only supports a background color and a text string. On mobile devices, the Python unpacking phase can take several seconds. A static string makes the app feel "frozen" or unpolished compared to native apps that use branded animations during initialization.
Code sample
Code
To reproduce
[tool.flet.android.app.boot_screen]
show = false
message = "Preparing the app for its first launch…"
Expected behavior
would like the ability to specify a Lottie JSON file or a Rive .riv file in the [tool.flet.app.boot_screen] configuration. This would allow a smooth, animated transition from the native Splash Screen to the Flet UI.
Supporting animations during the "unpacking" phase would significantly improve the user experience and perceived speed of Flet apps on Android and iOS.
