提取我的TextFormField小部件的方法后，我想使用TextedingController添加控制器，问题是如何将其放置在每个字段中，但是我将其全部提取到了方法，但是如果我输入了所有显示的内容，则输入字段：

这是我试图使用控制器的注册部分，但是我

Container buildSignupSection() {
     return Container(
       margin: EdgeInsets.only(top: 30),
       child: Form(
         key: _signUpFormKey,
         child: Column(
           children: [
             buildTextField(
               "xpresschop",
               "Name",
               true,
               false,
               false,
             ),
             buildTextField(
               "[email protected]",
               "email",
               false,
               false,
               true,
             ),
             buildTextField(
               "......",
               "password",
               false,
               true,
               false,
             ),
             buildTextField(
               "......",
               "Confirm password",
               false,
               true,
               false,
             ),
           ],
         ),
       ),
     );
   }

将其保留在下面

Widget buildTextField(String hintText, String labelText, bool isName,
      bool isPassword, bool isEmail) {
    return Padding(
      padding: const EdgeInsets.only(bottom: 10.0),
      child: Column(
        children: [
          TextFormField(
              controller: ,
            autocorrect: isAutoCorrect,
            obscureText: isPassword,

After extracting the method of my textformfield widget, I want to add controller to it using the TextEditingController,the issue is how to placed it in each fields but i have extracted it all to a method, but if I type anything it shows for all the input fields:

This is the signup part where I am trying to use the controller, but i kept it below

Container buildSignupSection() {
     return Container(
       margin: EdgeInsets.only(top: 30),
       child: Form(
         key: _signUpFormKey,
         child: Column(
           children: [
             buildTextField(
               "xpresschop",
               "Name",
               true,
               false,
               false,
             ),
             buildTextField(
               "[email protected]",
               "email",
               false,
               false,
               true,
             ),
             buildTextField(
               "......",
               "password",
               false,
               true,
               false,
             ),
             buildTextField(
               "......",
               "Confirm password",
               false,
               true,
               false,
             ),
           ],
         ),
       ),
     );
   }

How will i add it here

Widget buildTextField(String hintText, String labelText, bool isName,
      bool isPassword, bool isEmail) {
    return Padding(
      padding: const EdgeInsets.only(bottom: 10.0),
      child: Column(
        children: [
          TextFormField(
              controller: ,
            autocorrect: isAutoCorrect,
            obscureText: isPassword,

将不同的控制器添加到每个TextField，U可以将控制器作为参数传递到buildTextField方法，

 var nameController = TextEditingController();
 ...
 buildTextField( "xpresschop", "Name", true, false, false, nameController)
 ...

然后您的小部件将是：

Widget buildTextField(String hintText, String labelText, bool isName,
      bool isPassword, bool isEmail, TextEditingController myController) {
    return 
......
          TextFormField(
              controller:myController ,
....

Add different controller to each textfield, u can pass controller as parameter to buildTextField method

 var nameController = TextEditingController();
 ...
 buildTextField( "xpresschop", "Name", true, false, false, nameController)
 ...

then your widget would be:

Widget buildTextField(String hintText, String labelText, bool isName,
      bool isPassword, bool isEmail, TextEditingController myController) {
    return 
......
          TextFormField(
              controller:myController ,
....
