Flutter中open_file_safe与file_picker依赖冲突如何解决？

错误信息 #

Because file_picker >=5.0.0 depends on ffi ^2.0.1 and open_file_safe 3.2.3 depends on ffi ^1.0.0, file_picker >=5.0.0 is incompatible with open_file_safe 3.2.3.
And because no versions of open_file_safe match >3.2.3 <4.0.0, file_picker >=5.0.0 is incompatible with open_file_safe ^3.2.3.
So, because app depends on both open_file_safe ^3.2.3 and file_picker ^5.2.2, version solving failed.
pub get failed (1; So, because app depends on both open_file_safe ^3.2.3 and file_picker ^5.2.2, version solving failed.)

解决方案 #

• 升级open_file_safe到4.x版本：打开pubspec.yaml，把open_file_safe的版本改成^4.0.0或更高（如果有），新版本基本都适配了ffi^2.0.1，改完后运行pub get。
• 降级file_picker到4.x版本：如果暂时没法升级open_file_safe，就把file_picker的版本改成^4.6.1（4.x的最后一个稳定版），这个版本依赖ffi^1.0.0，和open_file_safe 3.2.3兼容，修改后执行pub get。
• 强制统一ffi版本（备选方案）：在pubspec.yaml里添加dependency_overrides，强制指定ffi为^2.0.1，但要注意这种方式可能有潜在兼容性问题，优先试试前两种方案。示例代码：

  dependency_overrides:
    ffi: ^2.0.1
