Closed as not planned
Description

- I have searched the existing package issues
- I have read the guide to filing a bug
What package does this bug report belong to?
image_picker
What target platforms are you seeing this bug on?
Android
Have you already upgraded your packages?
Yes
Dependency versions
pubspec.lock
Steps to reproduce
I am using the image_picker package to pick a file from the image : gallery (source) and read the Exif data. But when i check the GPS Info the latitude and longitude are set to [0/0, 0/0, 0/0]. I have seen a similar issue reported in 2022 #99817 but that was closed and #132827 reports of a missing Exif Tags.
The image has the GPS data.
This issue is only on Android as it works as expected on IOS.
image_picker package version : '1.0.4'.
Expected results
flutter: GPS GPSLatitudeRef: N
flutter: GPS GPSLatitude: [37, 39, 1324/25]
flutter: GPS GPSLongitudeRef: W
flutter: GPS GPSLongitude: [61, 22, 241/100]
flutter: GPS GPSAltitudeRef: 0
flutter: GPS GPSAltitude: 18859/100
flutter: GPS GPSImgDirectionRef: M
flutter: GPS GPSImgDirection: 340
