14-flutter-线性布局

Column 和 Row 都可以
通过 crossAxisAlignment 设置对齐方式

1. CrossAxisAlignment.start 起始位置对齐
2. CrossAxisAlignment.center 居中对齐
3. CrossAxisAlignment.end 末尾对齐

   body: Column(
   crossAxisAlignment: CrossAxisAlignment.end,
   children: <Widget>[
    Image.asset('static/pic/mg3414.jpg', width: 200, height: 300),
    Image.asset('static/pic/162.jpg', width: 200),
    Image.network('http://8.129.221.250:3000/uploads/fc3eace4355f22498f5d1008a942da30-NrJn4jqrY5Dd492d82806fe4d6b2a5707d806722350c.png'),
    Icon(Icons.zoom_out_sharp),
   ]
   ),

import 'package:flutter/material.dart';
// import 'package:english_words/english_words.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new MaterialApp(
      title: 'Welcome to Flutter',
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text('Welcome to Flutter12'),
        ),
        body: Column(
          crossAxisAlignment: CrossAxisAlignment.end,
          children: <Widget>[
            Image.asset('static/pic/mg3414.jpg', width: 200, height: 300),
            Image.asset('static/pic/162.jpg', width: 200),
            Image.network('http://8.129.221.250:3000/uploads/fc3eace4355f22498f5d1008a942da30-NrJn4jqrY5Dd492d82806fe4d6b2a5707d806722350c.png'),
            Icon(Icons.zoom_out_sharp),
          ]
        ),
      ),
    );
  }
