Fix Android build issues with Flutter 3.29.2 by updating dependencies

[dagyu]

I was having trouble building the Android app after upgrading to Flutter 3.29.2.
The main issue was caused by the open_filex dependency, which raise this error:

OpenFilePlugin.java:73: error: cannot find symbol
    public static void registerWith(PluginRegistry.Registrar registrar) {
                                                  ^
  symbol:   class Registrar
  location: interface PluginRegistry
1 error
3 warnings

FAILURE: Build failed with an exception.

I updated the packages in pubspec.yaml, including open_filex, to make them compatible with the latest Flutter version.
After the update, the Android build works as expected.
