AvMediaPlayer constructor

AvMediaPlayer({ String? initSource, double? initVolume, double? initSpeed, bool? initLooping, bool? initAutoPlay, int? initPosition, bool? initShowSubtitle, String? initPreferredSubtitleLanguage, String? initPreferredAudioLanguage, int? initMaxBitRate, Size? initMaxResolution, })

All parameters are optional, and can be changed later by calling the corresponding methods.
