Keep TextFields visible when keyboard comes up - #18291

@Aklil are you creating the TextEditingController for this input field inside the build() {...} method?
Is your input inside a ListView or another scrollable?

@zoechi yes I've them in a listview. Depending on the data I receive from an API, I build the input fields with TextEditingControllers.

//field  
final List<TextEditingController> _textEditingControllers = [];

//in build method the controllers are populated
 this._textEditingControllers.add(TextEditingController());

//then when each text input field is created, the controller is assigned as follows
TextFormField(
          controller: this._textEditingControllers[index],
          keyboardType: TextInputType.number,

final List<TextEditingController> _textEditingControllers = []; seems redundant because you don't use it in the other code.
this._textEditingControllers.add(TextEditingController()); means that the TextEditingController is recreated every time the tree is rebuilt.

@zoechi I have created the controllers in the initState() method. but still experiencing the same issue. Even tried to populate them in the constructor of the state class.

@zoechi Creating the global form key outside of the build method has resolved my issue. But I wanted to know whether it is a normal situation for the tree to be re-rendered when the text field is being focused and up on keyboard enter in the input. Thanks for your help.
