IN my Flutter app I have an input form that uses a Flutter autocomplete_textfield for one field. When creating new entries the form works fine. However, I need to also be able to use the form to edit records. Loading all other fields on the form from the record to be edited is working, I cannot find how to set the initial value of the autocomplete_textfield.

推荐答案
您可以为搜索字段创建控制器，并将其用作:TextEditingController _controller = TextEditingController();
并在init方法中添加:_controller.text = 'YOUR_TEXT_HERE';
也不要忘记将一个控制器添加到AutoCompleteTextField:AutoCompleteTextField<String>(controller: _controller,)
You can create controller to you Search Field and use it as:TextEditingController _controller = TextEditingController();
and in init method add:_controller.text = 'YOUR_TEXT_HERE';
also dont forget to add a controller to AutoCompleteTextField:AutoCompleteTextField<String>(controller: _controller,)
