Answer 1

在您的 email 和密碼TextField的onChanged中，
你：
將 TextField 中的 email 值設置為密碼

password = value;

並將您的密碼值從 TextField 設置為 email

email = value;

就換吧像這樣：

TextField(
          textAlign: TextAlign.center,
          style: TextStyle(
            color: Colors.black,
            fontSize: 20,
          ),
          decoration: InputDecoration(
            border: InputBorder.none,
            hintText: "Enter your email",
            hintStyle: kHintTextStyle,
          ),
          onChanged: (value) {
            email = value;
          },
        ),

 TextField(
          textAlign: TextAlign.center,
          style: TextStyle(
            color: Colors.black,
            fontSize: 20,
          ),
          decoration: InputDecoration(
            border: InputBorder.none,
            hintText: "Enter your password",
            hintStyle: kHintTextStyle,
          ),
          onChanged: (value) {
            password = value;
          },
        ),
