Reference

Use AdvancedMediaPicker.[MethodName] where MethodName is the same as the one on the interface.

    public interface IPicturePicker
    {
        Task<bool> ChoosePictureFromLibrary(string filePath, Action<Task<bool>>? saving = null, int maxPixelWidth=0, int maxPixelHeight=0, int percentQuality=80);

        /// <summary>
        /// Returns false if cancelled
        /// Note that saveToGallery can fails silently
        /// </summary>
        Task<bool> TakePicture(string filePath, Action<Task<bool>>? saving = null, int maxPixelWidth=0, int maxPixelHeight=0, int percentQuality=0, bool useFrontCamera=false, bool saveToGallery=false, CancellationToken cancel = default);

        bool HasCamera { get; }
