[Dart] - Rework Dart client generator to be flutter-compatible (#7418)

* copy mustache templates from dart generator

* Start with generator by copying the DartClientCodegen for now

* at least we know this is not for a browser..

* First working version for a simple swagger configuration

* remove browserClient parameter, since it doesn't make sense for flutter

* Take care of complex types to support object hierarchies

* add null safety

* add small test for options

* add flutter-petstore scripts

* generate flutter petstore output

* Add new flutter test project

* move generated client to make it usable

* use generated swagger petstore plugin

* add support for lists of objects

* add DateTime support

* fix listFromJson implementation

* fix NPEs in DateTime operations + place order in sample

* Small readme changes

* bugfixes

* Use flutter-compatible implementation as default dart implementation

* fix generated samples

* Make lists serializable, now all dart test cases are working again

* better list implementation

* use StringBuffer

* removed FlutterClientCodegen

* fix browser client

* fix dependencies

* swagger-browser-client for browserClient testcases

* fix scripts

* removed flutter scripts

* add map support and simplify code via using .toJson contract

* remove unneeded devDependencies

* Regenerated samples

* fix call to mapFromJson, it is not a constructor

* remove pointless string serialization

* regenerated dart samples

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
