+For the time being, the follow-dev branch is no longer used, but only the master branch is needed to unify the pub version number.
+
+New Feature:
+
+- It is now supported to set the compression target to png format.
+
+## 0.5.2
+
+Fix:
+
+- [#49](https://github.com/OpenFlutter/flutter_image_compress/issues/49): A problem of reading Exif information.
+
+## 0.5.1
+
+Change `reportError` with flutter stable version.
+
+**Breaking Change:**
+The autoCorrectionAngle parameter causes a number of situations to behave differently than `0.4.0`. See readme for details.
+
+## 0.5.0
+
+(don't use)
+
+**Breaking Change:**
+Because `FlutterError.reportError` method's param `context` type changed.

+## Why don't you use dart to do it
+
+Q：Dart already has image compression libraries. Why use native?
+
+A：For unknown reasons, image compression in Dart language is not efficient, even in release version. Using isolate does not solve the problem.
+
+## Usage
+
+```yaml
+dependencies:
+  flutter_image_compress: ^0.7.0
+```
+
+```dart
+import 'package:flutter_image_compress/flutter_image_compress.dart';
+```
+
+Use as:
+
+[See full example](https://github.com/OpenFlutter/flutter_image_compress/blob/master/example/lib/main.dart)
+
+There are several ways to use the library api.
+
+```dart
+
+  // 1. compress file and get Uint8List
+  Future<Uint8List> testCompressFile(File file) async {
+    var result = await FlutterImageCompress.compressWithFile(
+      file.absolute.path,
+      minWidth: 2300,
+      minHeight: 1500,
+      quality: 94,
+      rotate: 90,
+    );
+    print(file.lengthSync());
+    print(result.length);
+    return result;
+  }
+
+  // 2. compress file and get file.
+  Future<File> testCompressAndGetFile(File file, String targetPath) async {
+    var result = await FlutterImageCompress.compressAndGetFile(
+        file.absolute.path, targetPath,
+        quality: 88,
+        rotate: 180,
+      );
+
+    print(file.lengthSync());
+    print(result.lengthSync());
+
+    return result;
+  }
+
+  // 3. compress asset and get Uint8List.
+  Future<Uint8List> testCompressAsset(String assetName) async {
+    var list = await FlutterImageCompress.compressAssetImage(
+      assetName,
+      minHeight: 1920,
+      minWidth: 1080,
+      quality: 96,
+      rotate: 180,
+    );
+
+    return list;
+  }
+
+  // 4. compress Uint8List and get another Uint8List.
+  Future<Uint8List> testComporessList(Uint8List list) async {
+    var result = await FlutterImageCompress.compressWithList(
+      list,
+      minHeight: 1920,
+      minWidth: 1080,
+      quality: 96,
+      rotate: 135,
+    );
+    print(list.length);
+    print(result.length);
+    return result;
+  }
+```
+
+## About common params
+
+### minWidth and minHeight
+
+`minWidth` and `minHeight` are constraints on image scaling.
+
+For example, a 4000\*2000 image, `minWidth` set to 1920, `minHeight` set to 1080, the calculation is as follows:
+
+```dart
+// Using dart as an example, the actual implementation is Kotlin or OC.
+import 'dart:math' as math;
+
+void main() {
+  var scale = calcScale(
+    srcWidth: 4000,
+    srcHeight: 2000,
+    minWidth: 1920,
+    minHeight: 1080,
+  );
+
+  print("scale = $scale"); // scale = 1.8518518518518519
+  print("target width = ${4000 / scale}, height = ${2000 / scale}"); // target width = 2160.0, height = 1080.0
+}
+
+double calcScale({
+  double srcWidth,
+  double srcHeight,
+  double minWidth,
+  double minHeight,
+}) {
+  var scaleW = srcWidth / minWidth;
+  var scaleH = srcHeight / minHeight;
+
+  var scale = math.max(1.0, math.min(scaleW, scaleH));
+
+  return scale;
+}
+
+```
+
+If your image width is smaller than minWidth or height samller than minHeight, scale will be 1, that is, the size will not change.
+
+### rotate
+
+If you need to rotate the picture, use this parameter.
+
+### autoCorrectionAngle
+
+This property only exists in the version after 0.5.0.
+
+And for historical reasons, there may be conflicts with rotate attributes, which need to be self-corrected.
+
+Modify rotate to 0 or autoCorrectionAngle to false.
+
+### quality
+
+Quality of target image.
+
+If `format` is png, the param will be ignored in iOS.
+
+### format
+
+Supports jpeg or png, default is jpeg.
+
+The format class sign `enum CompressFormat`.
+
+Heif and webp Partially supported.
+
+#### Webp
+
+Support android by the system api (speed very nice).
+
+And support iOS, but However, no system implementation, using [third-party libraries](https://github.com/SDWebImage/SDWebImageWebPCoder) used, it is not recommended due to encoding speed. In the future, libwebp by google (c / c ++) may be used to do coding work, bypassing other three-party libraries, but there is no guarantee of implementation time.
+
+#### HEIF(Heic)
+
+##### Heif for iOS
+
+Only support iOS 11+.
+
+##### Heif for Android
+
+Use https://developer.android.com/reference/androidx/heifwriter/HeifWriter.html to implemation.
+
+Only support API 28+.
+
+And may require hardware encoder support, does not guarantee that all devices above API28 are available
+
+### inSampleSize
+
+The param is only support android.
+
+For a description of this parameter, see the [Android official website](https://developer.android.com/reference/android/graphics/BitmapFactory.Options.html#inSampleSize).
+
+### keepExif
+
+If this parameter is true, EXIF information is saved in the compressed result.
+
+Attention should be paid to the following points:
+
+1. Default value is false.
+2. Even if set to true, the direction attribute is not included.
+3. Only support jpg format, PNG format does not support.
+
+## Result
+
+The result of returning a List collection will not have null, but will always be an empty array.
+
+The returned file may be null. In addition, please decide for yourself whether the file exists.
+
+### About `List<int>` and `Uint8List`
+
+You may need to convert `List<int>` to `Uint8List` to display images.
+
+To use `Uint8List`, you need import package to your code like this:
+
+![img](https://raw.githubusercontent.com/CaiJingLong/asset_for_picgo/master/20190519111735.png)
+
+```dart
+final image = Uint8List.fromList(imageList)
+ImageProvider provider = MemoryImage(Uint8List.fromList(imageList));
+```
+
+Usage in `Image` Widget:
+
+```dart
+List<int> image = await testCompressFile(file);
+ImageProvider provider = MemoryImage(Uint8List.fromList(image));
+
+Image(
+  image: provider ?? AssetImage("img/img.jpg"),
+),
+```
+
+Write to file usage:
+
+```dart
+void writeToFile(List<int> image, String filePath) {
+  final file = File(filePath);
+  file.writeAsBytes(image, flush: true, mode: FileMode.write);
+}
+```
+
+## Runtime Error
+
+Because of some support issues, all APIs will be compatible with format and system compatibility, and an exception (UnsupportError) may be thrown, so if you insist on using webp and heic formats, please catch the exception yourself and use it on unsupported devices jpeg compression.
+
+Example:
+
+```dart
+Future<Uint8List> compressAndTryCatch(String path) async {
+    Uint8List result;
+    try {
+      result = await FlutterImageCompress.compressWithFile(path,
+          format: CompressFormat.heic);
+    } on UnsupportedError catch (e) {
+      print(e);
+      result = await FlutterImageCompress.compressWithFile(path,
+          format: CompressFormat.jpeg);
+    }
+    return result;
+  }
+```
+
+## Android
+
+You may need to update Kotlin to version `1.3.72` or higher.
+
+## iOS
+
+No problems currently found.
+
+## Troubleshooting or common error
+
+### Compressing returns `null`
+
+Sometimes, compressing will return null. You should check if you can read/write the file, and the parent folder of the target file must exist.
+
+For example, use the [path_provider](https://pub.dartlang.org/packages/path_provide) plugin to access some application folders, and use a permission plugin to request permission to access SD cards on Android/iOS.
+
+### Android build error
+
+```groovy
+Caused by: org.gradle.internal.event.ListenerNotificationException: Failed to notify project evaluation listener.
+        at org.gradle.internal.event.AbstractBroadcastDispatch.dispatch(AbstractBroadcastDispatch.java:86)
+        ...
+Caused by: java.lang.AbstractMethodError
+        at org.jetbrains.kotlin.gradle.plugin.KotlinPluginKt.resolveSubpluginArtifacts(KotlinPlugin.kt:776)
+        ...
+```
+
+See [flutter/flutter/issues#21473](https://github.com/flutter/flutter/issues/21473#issuecomment-420434339)
+
+You need to upgrade your Kotlin version to `1.2.71+`(recommended 1.3.72).
+
+If Flutter supports more platforms (Windows, Mac, Linux, etc) in the future and you use this library, propose an issue or PR!
+
+## About EXIF information
+
+Using this library, EXIF information will be removed by default.
+
+EXIF information can be retained by setting keepExif to true, but not `direction` information.
