最近 2 天我一直卡在这个问题上。
请帮忙。
谢谢。
鉴于您的问题源于分析器并且您的构建正在等待 auto_route_generator 库,并且该库的版本比您使用的版本更新,因为它只有 change 有“将分析器版本限制为“>=0.40.0 <2.0.0” 我猜猜你应该更新它。
对我来说,arpit 解决方案有效:“将 build_runner 降级到 1.10.2”。
(2020 年 11 月 27 日添加):
在其他情况下,如果其中有一些带有“//”的导入,则可能会出现问题,例如:
`import 'package:path//name.dart'.
这是一个正则表达式,用于查找同一行中包含“//”的“导入”:
(import).*?(//).*?
此解决方案取自https://github.com/google/json_serializable.dart/issues/738,参见dotdotcommadot answer。
我今天早些时候遇到了同样的问题。对我来说,有效的方法是删除所有测试文件并使 build_runner 降级到 1.10.2。我知道这不是最好的解决方案,但它是暂时的解决方法。
在我的例子中,我有两个生成源代码的包:floor
持久性包(生成类似于 moor
或 sqflite
)和用于测试的 mockito
.错误消息来自测试,例如:
[SEVERE] floor_generator:floor_generator on test/pace_string_test.dart:
NoSuchMethodError: The getter 'definingUnit' was called on null.
Receiver: null
Tried calling: definingUnit
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:54:5)
...
解决方案是替换我测试中的任何相关导入以打包 URI 导入 (as suggested by miDeb on Github)。所以我更换了
import '../lib/track_my_indoor_exercise/tcx/tcx_model.dart';
和
import 'package:track_my_indoor_exercise/tcx/tcx_model.dart';
在运行之后flutter pub run build_runner watch --delete-conflicting-outputs
构建运行器输出

最近 2 天我一直卡在这个问题上。 请帮忙。 谢谢。
鉴于您的问题源于分析器并且您的构建正在等待 auto_route_generator 库,并且该库的版本比您使用的版本更新,因为它只有 change 有“将分析器版本限制为“>=0.40.0 <2.0.0” 我猜猜你应该更新它。
对我来说,arpit 解决方案有效:“将 build_runner 降级到 1.10.2”。
(2020 年 11 月 27 日添加):
在其他情况下,如果其中有一些带有“//”的导入,则可能会出现问题,例如:
`import 'package:path//name.dart'.
这是一个正则表达式,用于查找同一行中包含“//”的“导入”:
(import).*?(//).*?
此解决方案取自https://github.com/google/json_serializable.dart/issues/738,参见dotdotcommadot answer。
我今天早些时候遇到了同样的问题。对我来说,有效的方法是删除所有测试文件并使 build_runner 降级到 1.10.2。我知道这不是最好的解决方案,但它是暂时的解决方法。
在我的例子中,我有两个生成源代码的包:floor
持久性包(生成类似于 moor
或 sqflite
)和用于测试的 mockito
.错误消息来自测试,例如:
[SEVERE] floor_generator:floor_generator on test/pace_string_test.dart:
NoSuchMethodError: The getter 'definingUnit' was called on null.
Receiver: null
Tried calling: definingUnit
#0 Object.noSuchMethod (dart:core-patch/object_patch.dart:54:5)
...
解决方案是替换我测试中的任何相关导入以打包 URI 导入 (as suggested by miDeb on Github)。所以我更换了
import '../lib/track_my_indoor_exercise/tcx/tcx_model.dart';
和
import 'package:track_my_indoor_exercise/tcx/tcx_model.dart';
