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,
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_app
description: A new Flutter project.
dependencies:
flutter:
sdk: flutter
dev_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
