如何解决颤动错误中的“作为前缀”

Question

The name 'LocationAccuracy' is defined in the libraries 'package:geolocation/geolocation.dart', 'package:geolocator/geolocator.dart' and 'package:location_platform_interface/location_platform_interface.dart (via package:location/location.dart)'.
Try using 'as prefix' for one of the import directives, or hiding the name from all but one of the imports.dartambiguous_import

Answer 1

此消息是因为在多个库中定义了

LocationAccuracy

。因此，您需要定义从哪个库获取此 LocationAccuracy。所以你需要在导入后指定一个前缀，如下所示：

import 'package:geolocation/geolocation.dart' as geo; // or whatever name you want
import 'package:geolocator/geolocator.dart' as geolocator; // or whatever name you want

然后具体要使用的

LocationAccuracy

可以这样参考：

geo.LocationAccuracy

或

geolocator.LocationAccuracy

Answer 2

您还可以使用隐藏 LocationAccuracy 的第二个建议，方法是在导入“package:geolocator/geolocator.dart”后添加此内容，如下所示：

import 'package:geolocator/geolocator.dart' hide LocationAccuracy;

Answer 3

将“package:flutter_archive/flutter_archive.dart”导入为zip； 你在哪里使用这个包 等待 zip.ZipFile.createFromDirectory( 源目录：临时目录， zip文件： zip文件， recurseSubDirs：真， );
