dependencies:
  photo_manager: $latest_version

import #

import 'package:photo_manager/photo_manager.dart';

use #

see the example/lib/main.dart

or see next

example #

  1. request permission

You must get the user's permission on android/ios.

var result = await PhotoManager.requestPermission();
if (result) {
    // success
} else {
    // fail
    /// if result is fail, you can call `PhotoManger.openSetting();`  to open android/ios applicaton's setting to get permission
}
  1. you get all of asset list (gallery)
List<AssetPathEntity> list = await PhotoManager.getAssetPathList();

or

List<AssetPathEntity> list = await PhotoManager.getImageAsset();

or

List<AssetPathEntity> list = await PhotoManager.getVideoAsset();
  1. get asset list from imagePath
List<AssetEntity> imageList = await data.assetList;
  1. use the AssetEntity
AssetEntity entity = imageList[0];

File file = await entity.file; // image file

List<int> fileData = await entity.fullData; // image/video file bytes

Uint8List thumbBytes = await entity.thumbData; // thumb data ,you can use Image.memory(thumbBytes); size is 64px*64px;

Uint8List thumbDataWithSize = await entity.thumbDataWithSize(width,height); //Just like thumbnails, you can specify your own size. unit is px;

AssetType type = entity.type; // the type of asset enum of other,image,video

Duration duration = await entity.duration; //if type is not video, then return null.

Usage #

About isCache #

If isCache of the getAssetPathList is true, method will return cache data. Invalid if no method with cache = false has been called before.

If the isCache = false method has not been invoked before, the data cannot be returned.

If releaseCache method is called, then cache will be clear, you must call getAssetPathList(isCache:false) before getAssetPathList(isCache:true)

Create AssetEntity with id

the id is AssetEntity.id

AssetEntity asset = await createAssetEntityWithId(id);

When this method is called, the image corresponding to ID has been deleted, and the return value is null.

observer #

use addChangeCallback to regiser observe.

PhotoManager.addChangeCallback(changeNotify);
PhotoManager.startChangeNotify();
PhotoManager.removeChangeCallback(changeNotify);
PhotoManager.stopChangeNotify();

iOS plist config #

Because the album is a privacy privilege, you need user permission to access it. You must to modify the Info.plist file in Runner project.

like next

    <key>NSPhotoLibraryUsageDescription</key>
    <string>App need your agree, can visit your album</string>

xcode like image in xcode

android config #

about androidX #

Google recommends completing all support-to-AndroidX migrations in 2019. Documentation is also provided.

This library has been migrated in version 0.2.2, but it brings a problem. Sometimes your upstream library has not been migrated yet. At this time, you need to add an option to deal with this problem.

The complete migration method can be consulted gitbook.

glide #

Android native use glide to create image thumb bytes, version is 4.9.0.

If your other android library use the library, and version is not same, then you need edit your android project's build.gradle.

rootProject.allprojects {

    subprojects {
        project.configurations.all {
            resolutionStrategy.eachDependency { details ->
                if (details.requested.group == 'com.github.bumptech.glide'
                        && details.requested.name.contains('glide')) {
                    details.useVersion "4.9.0"
                }
            }
        }
    }
}
