我正在尝试运行我的 flutter 应用程序，但出现这些错误？

Question

这是错误信息

当前Dart SDK版本为2.13.4。

因为test >=1.16.0-nullsafety <1.16.0-nullsafety.8需要SDK版本>=2.10.0-0 <2.12.0和test >=1.16.0-nullsafety.8 <1.16.0-nullsafety.18取决于typed_data >=1.3.0-nullsafety <1.3.0，test >=1.16.0-nullsafety <1.16.0-nullsafety.18要求typed_data >=1.3.0-nullsafety <1.3.0。 又因为 test >=1.16.0-nullsafety.18 <1.16.0-nullsafety.19 依赖于 test_api 0.2.19-nullsafety.7 而 test >=1.13.0 <1.14.5 依赖于 test_api 0.2.15, test > =1.13.0 <1.14.5-∞ or >=1.16.0-nullsafety <1.16.0-nullsafety.19 requires typed_data >=1.3.0-nullsafety <1.3.0 or test_api 0.2.15 or 0.2.19-nullsafety .7. 又因为test >=1.14.5 <1.15.0 依赖于test_api 0.2.16 and test >=1.15.0 <1.15.3 依赖于test_api 0.2.17, test >=1.13.0 <1.15.3-∞ or > =1.16.0-nullsafety <1.16.0-nullsafety.19 要求 typed_data >=1.3.0-nullsafety <1.3.0 或 test_api 0.2.15 或 0.2.16 或 0.2.17 或 0.2.19-nullsafety.7。 又因为test >=1.15.3 <1.15.5依赖于test_api 0.2.18和test >=1.15.5 <1.16.0-nullsafety依赖于test_api 0.2.18+1, test >=1.13.0 <1.16.0 -nullsafety.19 需要 typed_data >=1.3.0-nullsafety <1.3.0 或 test_api 0.2.15 或 0.2.16 或 0.2.17 或 0.2.18 或 0.2.18+1 或 0.2.19-nullsafety.7。 又因为test >=1.16.0-nullsafety.19 <1.16.6 依赖于test_api 0.2.19 而test >=1.18.0 需要SDK version >=2.14.0 <3.0.0, test >=1.13.0 <1.16 .6-∞ or >=1.18.0 requires test_api 0.2.15 or 0.2.16 or 0.2.17 or 0.2.18 or 0.2.18+1 or 0.2.19-nullsafety.7 or 0.2.19 or typed_data >=1.3 .0-空安全 <1.3.0。 并且因为来自 sdk 的每个版本的 integration_test 都依赖于 test_api 0.3.0 和 typed_data 1.3.0，所以来自 sdk 的 integration_test 与 test >=1.13.0 <1.16.6-∞ or >=1.18.0 不兼容。 并且因为 test >=1.16.6 <1.18.0 取决于 shelf_static ^1.0.0 取决于 convert ^3.0.0，如果 integration_test 来自 sdk 并且 test >=1.13.0 然后转换 ^3.0.0。 并且因为 flutter_svg 0.17.4 依赖于 xml ^3.3.1 而依赖于 convert ^2.1.0，所以来自 sdk 或 test >=1.13.0 或 flutter_svg 0.17.4 的任何一个 integration_test 之一必须为 false。 并且因为没有版本的 flutter_svg 匹配 >0.17.4 <0.18.0 并且 test_ui 依赖于 flutter_svg ^0.17.4，来自 sdk 的 integration_test 与 test >=1.13.0 不兼容。 所以，因为test_ui同时依赖integration_test any from sdk和test ^1.13.0，所以版本解析失败。 pub get failed (1; 因此，因为 test_ui 依赖于 integration_test any from sdk 和 test ^1.13.0，版本解析失败。)

有人可以帮忙吗？

这是我的 pubspec.yaml 文件

你能试试这个吗？

现在你的 dart sdk 当前版本：2.13.4

请将您的 dart 版本 2.13.4 更改为 2.10.0。
