let param type to be public

[windrunner414]

the param type is private _ParameterList, it cause i can't specify type annotation, dart analysis will report this warning (I use flutter project analysis_option)

Using list is inspired by koin, of course using map is also possible. @windrunner414

@ditclear I use code generator to use it easier and named parameters but _ParameterList is private, I can't specify type annotation like single(({ParameterList param})=>x()) Although it won't cause any problems, but dart analysis server report a warning if u open related option I think ParameterList should be public

You can copy the dartin.dart file and make _ParameterList public
