just_audio_windows Cannot seek duration on Windows

Issue

 [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: PlatformException(position, the position argument can not be null, null, null)

Using just on Windows 10_ audio_ Windows to compile the fluent application, but the player cannot seek duration

Solution

After 1 day debugging I solve this issue with changing line 225 in the player.hpp file inside just_audio_windows/windows/player.hpp.

change it from:

const auto* position = std::get_if<int_64_t>(ValueOrNull(*args, "position"));

to:

const auto* position = std::get_if<int>(ValueOrNull(*args, "position"));
