Question

我最近将最新版本升级到Flutter。结果，我的应用程序将无法加载并立即失败。该错误似乎是由于Flutter版本引起的。我曾尝试降级，但没有成功。

这是控制台的输出。

Running "flutter pub get" in source...
Because every version of flutter_test from sdk depends on vector_math 2.1.0-nullsafety.3 and fstore depends on vector_math 2.0.8, flutter_test from sdk is forbidden.
So, because fstore depends on flutter_test any from sdk, version solving failed.
pub get failed (1; So, because fstore depends on flutter_test any from sdk, version solving failed.)

我尝试过更改开发频道并进行升级。这没用。我改用稳定版并进行了升级-这也不起作用。我试图降级并还原，但也没有用。

关于如何解决此问题的任何想法？ -我有点新手编码！

我的pubspec.yaml是：

name: fstore
description: Mobile commerce app by Flutter

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

Answer 1

错误：Because every version of flutter_test from sdk depends on...

意味着flutter_test依赖于版本低于您在另一个依赖项中指定的依赖项。

要解决此问题，请打开pubspec.yaml，然后删除问题依赖项的版本号：vector_math: 2.0.8 >> vector_math:

Because every version of flutter_test from sdk depends on... flutter_test from sdk is forbidden, version solving failed

失败的'flutter pub get'-“因此，由于fstore依赖于sdk中的flutter_test，因此版本解析失败。”
