Make example more simple

[Trung15010802]

I'm trying to use router with wolt_modal_sheet, but the example is too complicated. The sample should be simple without third-party package like bloc

@Trung15010802 I will have a workshop in Flutter&Friends on this topic and I will try to simplify as much as possible. Thanks for the input.

@Trung15010802 thanks for getting back to us with this. I agree and I have an ongoing work on the README and sample apps with coordination with @ulusoyca :) You can track the umbrella issue here --> #284

We do have a copy paste an example on the README.md now. Have you tried that, it only expects you to have wolt_modal_sheet.
