这是signup1.dart函数，它将控制器从signup1转移到signup2
void navigateToSignup2() {
if (emailController.text.isNotEmpty &&
fullNameController.text.isNotEmpty &&
phoneNumberController.text.isNotEmpty &&
passwordController.text.isNotEmpty) {
// Passing data from Signup1 to Signup2
Navigator.push(
context,
MaterialPageRoute(
builder: (context) => SignUp2(
fullName: fullNameController.text,
email: emailController.text,
phone: phoneNumberController.text,
password: passwordController.text,
),
),
);
} else {
setState(() {
_isNotValidate = true;
});
}
}

我已经尝试过-
headers: {"Content-Type": "application/json"}, 之前 标题：{“Content-Type”：“Application/json”}， 我的移动设备和笔记本电脑连接到同一 wifi 网络 手动添加端口和IP到android studio 我还与邮递员检查过，后端工作正常，数据存储在 mongodb 中。
我不太明白你的错误， 但如果你的情况是： 您正在同一台笔记本电脑上运行后端，并且您正在尝试从 flutter 模拟器访问它，您所要做的就是 http://10.0.2.2:5237/{your end point} 端口号就是您必须根据后端端口更改的所有内容，因为 Android 安全性拒绝访问本地网址
