Flutter邮箱验证插件check_disposable_email的使用

Check Email disposable Package

该包用于检查用户提供的电子邮件地址是否为临时邮箱。

什么是临时邮箱？

临时邮箱（也称为一次性邮箱、临时邮箱或虚假邮箱）是一种仅在短时间内使用的邮箱地址，使用后即被丢弃。这些邮箱地址通常由各种在线服务或网站提供，允许用户注册服务或访问内容而不使用其主要或个人邮箱地址。

特性

• ✅ 检查临时（虚假）邮箱地址

安装

dependencies:
  check_disposable_email: ^0.0.1

使用

import 'package:check_disposable_email/check_disposable_email.dart';

bool isValidEmail = Disposable.instance.hasValidEmail(here your email address);

if(isValidEmail){
   // TODO 然后执行某些任务
}else{
   // TODO 显示邮箱错误
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({
    super.key,
  });

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

final controller = TextEditingController();
bool? isValidEmail;

class _MyHomePageState extends State<MyHomePage> {
  [@override](/user/override)
