Static Methods
-
cacheImageFile(
String imageUrl) → Future< File?> - 前提：你使用了cached_network_image来加载图片，根据图片url返回其缓存的File对象
-
openAppPermissionSettings(
) → Future< bool> -
saveBytes2Album(
Uint8List bytes, {ImageByteFormat format = ImageByteFormat.png, String? fileName, int quality = 80}) → Future< SaveResult?> - 将图片保存到相册，返回路径
-
saveCacheImage2Album(
String imageUrl, {String? fileName}) → Future< SaveResult?> - 前提：你使用了cached_network_image来加载图片，将图片url保存到相册，返回路径
-
saveFile2Album(
String filePath, {String? fileName}) → Future< SaveResult?> - 将图片文件保存到相册，返回路径
-
saveImage2Album(
ByteData bytes, {ImageByteFormat format = ImageByteFormat.png, String? fileName, int quality = 80}) → Future< SaveResult?> - 将图片保存到相册，返回路径
-
saveWidget2Album(
GlobalKey< State< key, {ImageByteFormat format = ImageByteFormat.png, String? fileName, int quality = 80}) → Future<StatefulWidget> >SaveResult?> - 将widget转为图片保存到相册，返回路径 key所在节点必须是RepaintBoundary节点，否则会报错，截取 RenderRepaintBoundary 的内容
-
widget2image(
GlobalKey< State< key, {ImageByteFormat format = ImageByteFormat.png}) → Future<StatefulWidget> >ByteData?> - key所在节点必须是RepaintBoundary节点，否则会报错，截取 RenderRepaintBoundary 的内容
