🎯 Goal

Allow dismissing commands overlay and attachments picker on message list tap.

📝 Summary

• Allows dismissing the commands overlay when tapping the message list
• Allows dismissing the keyboard attachments picker when tapping the message list

Both are enabled by default since it is what most customers will want. A feature flag has been added for customers who want to disable this.

🛠 Implementation

In order not to cause a breaking change, I used NSNotifications to notify the composer view that it needs to hide the commands overlay or the attachments picker from the channel view.

Note

At the moment, the commands overlay is coupled with the command in the composer. So if there is a command selected already, hiding the overlay will remove the command from the composer. Changing this is out of scope since it would probably cause breaking changes, but in the future, it would be nice if these were decoupled like in UIKit.

🧪 Manual Testing Notes

Commands Overlay

1. Open a channel
2. Tap on the input composer to show the keyboard
3. Type "/..."
4. Tap on the message list
5. The commands overlay should be hidden

Attachments Picker

1. Open a channel
2. Tap on the input composer to show the keyboard
3. Type on the attachments icon
4. Tap on the message list
5. The attachments picker should be hidden
