[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.

+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell Swagger Codgen to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
