You do not have to do
controller..text = text;
inside onChanged
because the controller’s text automatically changes once you connect it to TextField.
The reason is once you set some text to controller
, it re-applies
the text thus moving the cursor at front.
In your case :
TextField(
decoration: InputDecoration(
border: InputBorder.none
),
controller: controller,
autofocus: true,
onChanged: (text) {},
maxLines: 8,
)
should solve the issue.
