Explaining the problem:
The search-bar has no way of dismissing an open keyboard. This makes the search-bar a quite unusable as the normal user pattern is that the user search for something and then press the item and gets navigated there. On Android (at least on >= 5.x), the open keyboard will continue to stay open, even on the new page.
Referring to the question on Github, anyone how to do that for Nativescript-Vue and not for Nativescript with Typescript
Updated:
Added Playground: https://play.nativescript.org/?template=play-vue&id=hrrcW9
If I minimize the app, then click on it again, the keyboard pops open again.
