getMultiImages static method

Future<List?> getMultiImages({ required ImageType outputType, })

of Future returned depending on outputType :

• ImageType.file return a html.File list of the selected images.

• ImageType.bytes return a Uint8List list of the selected images.

• ImageType.widget return an Image.memory list using the images' bytes.

List<html.File> imgFiles = await getMultiImages(ImageType.file);
List<Uint8List> imgBytes = await getMultiImages(ImageType.bytes);
List<Image> imgWidgets = await getMultiImages(ImageType.widget);
