技术刚刚好经历

近几年,移动端跨平台开发技术层出不穷,从Facebook家的ReactNative,到阿里家WEEX,前端技术在移动端跨平台开发中大展身手,技术刚刚好作为一名Android开发,经历了从Reactjs到Vuejs的不断学习。而在2018年,我们的主角变成了Flutter,这是Goolge开源的一个移动端跨平台解决方案,可以快速开发精美的移动App。希望跟大家一起学习,一起进步!

今天我来介绍一个简单入门的flutter应用,


项目结构

main.dart文件

import 'package:flutter/material.dart';void main() {  runApp(MaterialApp(      // Title      title: "Simple Material App",      // Home      home: Scaffold(        // Appbar        appBar: AppBar(          // Title          title: Text("Simple Material App"),        ),        // Body        body: Container(          // Center the content          child: Center(            // Add Text            child: Text("Hello World!"),          ),        ),      )));}

pubspec.yaml文件

name: simple_material_appdescription: A new Flutter project.dependencies:  flutter:    sdk: flutterdev_dependencies:  flutter_test:    sdk: flutter# For information on the generic Dart part of this file, see the# following page: https://www.dartlang.org/tools/pub/pubspec# The following section is specific to Flutter.flutter:  # The following line ensures that the Material Icons font is  # included with your application, so that you can use the icons in  # the Icons class.  uses-material-design: true  # To add assets to your application, add an assets section, like this:  # assets:  #  - images/a_dot_burr.jpeg  #  - images/a_dot_ham.jpeg  # An image asset can refer to one or more resolution-specific "variants", see  # https://flutter.io/assets-and-images/.  # To add assets from package dependencies, first ensure the asset  # is in the lib/ directory of the dependency. Then,  # refer to the asset with a path prefixed with  # `packages/PACKAGE_NAME/`. The `lib/` is implied, do not  # include `lib/` in the asset path.  #  # Here is an example:  #  # assets:  #  - packages/PACKAGE_NAME/path/to/asset  # To add custom fonts to your application, add a fonts section here,  # in this "flutter" section. Each entry in this list should have a  # "family" key with the font family name, and a "fonts" key with a  # list giving the asset and other descriptors for the font. For  # example:  # fonts:  #   - family: Schyler  #     fonts:  #       - asset: fonts/Schyler-Regular.ttf  #       - asset: fonts/Schyler-Italic.ttf  #         style: italic  #   - family: Trajan Pro  #     fonts:  #       - asset: fonts/TrajanPro.ttf  #       - asset: fonts/TrajanPro_Bold.ttf  #         weight: 700
