程式執行根目錄

import 'dart:ui';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
void main() {
  runApp(MyApp());
}
/// 根目錄 Activity  ViewController
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
      home: MyHomePage(),
    );
  }

預設顯示的首頁面

///預設載入顯示的首頁面
class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key}) : super(key: key);
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
  ///使用者名稱使用
  late final TextEditingController _nameController = TextEditingController();
  ///密碼輸入框使用
  late final TextEditingController _passwordController =
      TextEditingController();
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        width: double.infinity,
        height: double.infinity,
        child: Stack(
          children: [
            //第一層 背景圖片
            buildFunction1(),
            //第二層 高斯模糊
            buildFunction2(),
            //第三層 登入輸入層
            buildFunction3(),
          ],
        ),
      ),
    );
  }
... ... 這裡是相應的方法塊
}

顯示的一個背景圖

  buildFunction1() {
    return Positioned.fill(
      child: Image.asset(
        "images/loginbg.png",
        fit: BoxFit.fill,
      ),
    );
  }

高斯模糊

  buildFunction2() {
    return Positioned.fill(
      child: BackdropFilter(
        filter: ImageFilter.blur(sigmaX: 3, sigmaY: 3),
        child: Container(
          color: Colors.white.withOpacity(0.4),
        ),
      ),
    );
  }

登入輸入層

buildFunction3() {
    return Positioned.fill(
      child: Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          SizedBox(
            width: 300,
            child: TextField(
              controller: _nameController,
              decoration: const InputDecoration(
                hintText: "請輸入使用者名稱",
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.all(Radius.circular(33)),
                  borderSide: BorderSide(
                    color: Colors.grey,
                  ),
                ),
              ),
            ),
          ),
          const SizedBox(height: 20),
          SizedBox(
            width: 300,
            child: TextField(
              controller: _passwordController,
              decoration: const InputDecoration(
                hintText: "請輸入密碼",
                border: OutlineInputBorder(
                  borderRadius: BorderRadius.all(Radius.circular(33)),
                  borderSide: BorderSide(
                    color: Colors.grey,
                  ),
                ),
              ),
            ),
          ),
          const SizedBox(height: 40),
          SizedBox(
            width: 300,
            height: 48,
            child: ClipRRect(
              borderRadius: const BorderRadius.all(Radius.circular(33)),
              child: ElevatedButton(
                onPressed: () {
                  String name = _nameController.text;
                  String password = _passwordController.text;
                  print("獲取到的內容是 $name  $password");
                },
                child: const Text("登入"),
              ),
            ),
          )
        ],
      ),
    );
  }
