[FR] Navigate between `chips` in a Multiselect cell

[Xazin]

Description

When changing a Multiselect cell, I want to be able to navigate between chips with arrows/mouse, and be able to use backspace to remove chips, and be able to add new chips at any position my cursor is at.

Impact

Keyboard hackers will have an easier time

Hey Rawat, this is quite the advanced feature. It requires replicating similar behaviour to that of a Chip Input Field commonly known from Angular (Material).

If you're new to Flutter I suggest picking another issue.

If you're still up for it let me know and I will assign you.👌

I'm not sure this is resolved how I envisioned it.

1. Up/down is fine, but if I can't deselect with enter the target in multi-select, then it's not functional.
2. I was thinking about left to right when I made this issue, since that is how most chip inputs work, but up/down would also work, only in the case where I want to remove one chip (and there are 2 chips), if there are 100 options, I'll have to use up/down to find the chip rather than being able to just press left arrow key and then delete.
