   discussion on #8606

   Since I was confused here: that's #8606 on flutter/engine, not this repo.

   ---

   It seems there is more blocking this than the simple matter of implementing it in the engine.

   I gather that iOS does not actually expose key-level events in its public API. Flutter would only have "insertText" and "deleteBackward" and "UIKeyCommand" events to work with, and mapping those back to the USB keypresses that generated them is not feasible.

   Maybe the situation is different on iOS 13 (but probably not by much). At the very least, from the comments on this WebKit bug, it sounds like a best-effort implementation could handle e.g. arrow keys on iOS 13, but not earlier versions. I certainly don't see the full picture of how close to an implementation of RawKeyboardEvent for iOS it's possible to get, but it seems the answer is "not very close". (I see no way to detect keydown vs. keyup, for example, as one might need for e.g. games that use WASD keys for movement.)

   iPadOS 13.4 (March 24 release) emphasized magic keyboard/trackpad support for 2018 iPad Pro, more users may be hitting this.

   Any updates on it ? iOS allows external bluetooth keyboard to be connected so is it possible to detect keyboard key presses ?

   One of my app needs to detect shortcuts like Shift+1, or Ctrl-Z etc and looking for solutions.

    Yes, we have solved this with a platform channel and UIKey in our project.
