I have a text field that I search with. I use the follwing codes:

TextField(
  controller: searchController,
  maxLines: 1,
  autofocus: true,
  onSubmitted: _search(),
),

_search(){
    print('here');
  }

But in output _serach method is called in a infinite loop when I submit text field. I want to call _search method one time.

CodePudding user response：

Well, first of all onSubmitted must be void Function (String?), while you passing void Function(). Try Something like this, it should work. At least it works for me:

TextField(
    controller: _controller,
    onSubmitted: (String value) async {
        await _performSearch(value);
    },
),
