Disable a text edit field in flutter

Question

I need to disable TextFormField occasionally. I couldn\'t find a flag in the widget, or the controller to simply make it read only or disable. What is the best way to do it?

Answer 1

There is now a way to disable TextField and TextFormField. See github here. Use it like this:

TextField(enabled: false)

Answer 2

This is another way of somehow disabling a TextField but keeping it's functionality. I mean for onTap usage

TextField(
    enableInteractiveSelection: false,
    onTap: () { FocusScope.of(context).requestFocus(new FocusNode()); },
)

• enableInteractiveSelection

  will disable content selection of TextField
  
  

• FocusScope.of(context).requestFocus(new FocusNode());

  change the focus to an unused focus node

Using this way, you can still touch TextField but can't type in it or select it's content. Believe me it's going to be useful sometimes ( datepicker, timepicker, ... ) :)

Answer 3

Similar to readonly like in html

TextField(
    enableInteractiveSelection: false,
    focusNode: FocusNode(),
)

This can response to onTap.

Similar to disabled like in html

TextField(
    enable: false
)

This can not response to onTap.

Answer 4

TextFormField(
readOnly: true,
)

Answer 5

TextField and TextFormField both have an argument called enabled. You can control it using a boolean variable. enabled=true means it will act as an editing text field whereas enabled=false will disable the TextField.

Answer 6

Use readOnly: true

TextField(
  readOnly: true,
  controller: controller,
  obscureText: obscureText,
  onChanged: (value) {
    onValueChange();
  },
  style: TextStyle(
    color: ColorResource.COLOR_292828,
    fontFamily: Font.AvenirLTProMedium.value,
    fontSize: ScreenUtil().setHeight(Size.FOURTEEN)),
    decoration: InputDecoration(
    border: InputBorder.none,
    hintText: hint,
    hintStyle: TextStyle(
      fontSize: ScreenUtil().setHeight(Size.FOURTEEN),
      color: ColorResource.COLOR_HINT,
      fontFamily: Font.AvenirLTProBook.value)),
  ),
