由于 pub 线上插件  很可能依赖了 其他第三方pub 包；

而我们 自己有必须要依赖 某一个指定版本的  冲突的 pub 的时候；我们强制 统一版本：

Because chewie 1.2.2 depends on provider ^5.0.0 and no versions of chewie match >1.2.2 <2.0.0, chewie ^1.2.2 requires provider ^5.0.0.
So, because bilibili depends on both chewie ^1.2.2 and provider 6.0.0, version solving failed.
pub get failed (1; So, because bilibili depends on both chewie ^1.2.2 and provider 6.0.0, version solving failed.)

# 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.

# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.
