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,
)
