A different SOLUTION for those who have problems with events

[vk-573]

The events are not triggerred for me for X reasons, but I found a solution for my use case and since I'm not the only one here with this problem...

only for thoses who got TextField(s) in your business logic
You can check if the keyboard is visible or not by the NodeFocus.hasFocus property of your TextField
which have aswell a listener.

YourNodeFocus.addListener(() { print("Has focus: " + _nodeName.hasFocus.toString()); if (YourNodeName.hasFocus) { // keyboard visible } else { // keyboard hidden } });

Scotch solutions.

I fount the Focus() implementation easier:

Focus(
  child: TextFormField(...),
  onFocusChange: (hasFocus) {
    if(hasFocus) {
      // do staff
    }
  },
)
