执行pub get后，我收到下列错误（第一次建置）

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.)

我尝试运行pub get命令，并希望它能成功运行，没有任何错误。
