Fix exif rotation for flutter #

pub package

Flutter plugin that fixes the picture orientation for some devices. In some devices the exif data shows picture in landscape mode when they're actually in portrait. This plugin fixes the orientation for pictures taken with those devices.

Every version of Android is supported. iOS implemented by @Bhagatcliffex

Installation #

Add flutter_exif_rotation as a dependency in your pubsec.yaml

Android #

Add this in your AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
