What are the differences between image picker vs file picker in flutter
An image picker in Flutter is a plugin/library that “allows you to select an image from the device's image library” or “take a new picture with the camera.” A file picker, on the other hand, allows you to select any type of file from the device's file system.
In other words, an image picker is specifically for selecting image files, while a file picker “can be used to select any type of file”, including images, documents, audio files, etc.

(double? maxWidth, double? maxHeight, int? quality) async {
try {
final List<XFile> pickedFileList = await _picker.pickMultiImage(
maxWidth: maxWidth,
maxHeight: maxHeight,
imageQuality: quality,
);
setState(() {
_imageFileList = pickedFileList;
});
} catch (e) {
setState(() {
_pickImageError = e;
});
}
});// Single image selection.
await _displayPickImageDialog(context!,
(double? maxWidth, double? maxHeight, int? quality) async {
try {
final XFile? pickedFile = await _picker.pickImage(
source: source,
maxWidth: maxWidth,
maxHeight: maxHeight,
imageQuality: quality,
);
setState(() {
_setImageFileListFromFile(pickedFile);
});

setState(() {
_pickImageError = e;
});
}
});.
