I want to change the image quality for picked image, but I got this error. Does anyone know how to fix this? (I got an image from iOS device.)
image_picker: compressing is not supported for type (null). Returning the image with original quality
Future getImageFromCam() async {
File image;
try {
image = await ImagePicker.pickImage(
source: ImageSource.camera, imageQuality: 90);
} on Exception {
_showDialog(context);
}
}
According to source code, compress image only support JPEG
and according to this discussion https://discussions.apple.com/thread/8319465
All photos taken with the camera will be JPG, unless you go to Settings/Camera - Formats and choose High Efficiency. But High Efficiency will make the photos HEIF,
So you can check your camera setting with this reference https://www.mactrast.com/2017/10/set-iphones-camera-back-saving-photos-jpeg-ios-11/
IOS part
(NSData *)convertImage:(UIImage *)image
usingType:(FLTImagePickerMIMEType)type
quality:(nullable NSNumber *)quality {
if (quality && type != FLTImagePickerMIMETypeJPEG) {
NSLog(@"image_picker: compressing is not supported for type %@. Returning the image with "
@"original quality",
[FLTImagePickerMetaDataUtil imageTypeSuffixFromType:type]);
}
Dart part https://github.com/flutter/plugins/blob/master/packages/image_picker/lib/image_picker.dart
/// The `imageQuality` argument modifies the quality of the image, ranging from 0-100
/// where 100 is the original/max quality. If `imageQuality` is null, the image with
