[REQ][dart] Dart full OAS3 support

See original GitHub issue

This is an epic to track remaining work for full dart/dart-dio OAS3 support.

General:

OAS3 fake petstore contains a model called File. This is generated as a separate model in the Go client but as java.io.File in Java/Kotlin. It should probably be a separate model. Currently this leads to compile errors. (addressed by https://github.com/OpenAPITools/openapi-generator/pull/8198)

Dart:

There are problems regarding deserialization of maps, de-serialization code is trying to call Map.mapFromJson. There are open issues for this and the problem is now evident in the generated fake petstore. Related issues: https://github.com/OpenAPITools/openapi-generator/issues/8029
De-serialization of maps of maps e.g. Map<String, Map<String, String>>
De-serialization of maps of enums e.g. Map<String, Enum>
De-serialization of list of list of model e.g. List<List<ReadOnlyFirst>>
Support enums of type double, de-serialization via switch statement doesn’t work here
De-serialization of List<Object> tries to call Object.mapFromJson
OAS3 fake petstore contains a model called Client, this conflict with http.Client (addressed by https://github.com/OpenAPITools/openapi-generator/pull/8198)

Dart-Dio:

Compile errors regarding header parameters of type bool and List, basically everything that is not a String (addressed by #8191)

@kuhnroyal I’ve downloaded the latest master (this project could suggest a clone with depth=1 btw) and built the package… it fixed some issues (inline enum probably), but still it had problems, so I fixed them for myself.

Here’s my commit https://github.com/Grohden/openapi-generator/commit/72c8e1531198e595e116d811173d2f2a6d558983, maybe I will open a PR later… but all those fixes were for my project and I can’t guarantee that all those casts will work (I’ve tested a single method in runtime and it worked)

In any case the project wasn’t even compiling without them, so it’s better than nothing.

Edit: had to ammend a change in the commit, I’ve update its URL

@Grohden If you have specific solutions to the some of the json mapping problems, please don’t hesitate to post them here. The dart generator is not my primary focus so any help is appreciated.
