Detect ‘enter key’ press in flutter

by

if you are using TextField then you have to add onSubmitted in your text field to detect when user press Enter key. For my case, I changed Done in keyboard to TextInputAction.Search. It also works for TextInputAction.Done too. here is a sample code

   TextField(
    onSubmitted: (value){
      //value is entered text after ENTER press
      //you can also call any function here or make setState() to assign value to other variable
    },
    textInputAction: TextInputAction.search,
  )
