- small comment fix (https://github.com/jonataslaw/getx/pull/560#commitcomment-42045326)
- added `RxBool.toggle()`as an easy shortcut for switching true/false values.
- added `_RxImp.nil()` to easily set the value to `null` (`nil` comes from LISP :P) seems to be a useful sometimes, for instance if using `RxString` in `TextField.decoration.errorText` is the only way to avoid the "error state".
- adds missing docs to Rx classes.

fix(lint/analyser): Added analyser + effective dart

- fixes #465
- iOS has an exception to the rule, when no Curve is defined, it doesn't use linearTransition in `CupertinoPages` (`Transition.cupertino/native/default`) and fullscreen dialogs so it applies the Curve, or use the default one.
It might be smarter, maybe, to also enforce the `animation` duration to stay in platforms defaults.
- had to change `CupertinoTransitions.buildTransitions` params in order to make the check and keep the code change small.
