Flutter 开发从 0 到 1

今天开始又要下班了,你的假期工作实现如何啊?因为平时加班太多了,切实挤不出更多工夫,从开始想用 Flutter《Flutter 开发从 0 到 1(一)需要与筹备》写一个残缺的 APP 曾经过来三个月了,然而我没有遗记,这个国庆工夫我终于实现了。Flutter 的确弱小,不止跨平台,还反对桌面利用,包含 Window、macOS、Linux,以及 Web 利用,真正一套代码,全平台反对,野心可见一斑。

以上我尝试过了,打包成了 APK、macOS 桌面利用、Web 利用没问题,只能用两个字形容 Flutter:牛皮,明天先分享这个 APP 源码。

大体性能如下:

页面 知识点 成果预览
框架 1、右滑菜单;2、我的珍藏
博客列表 1、布局;2、ListView 下拉刷新好和加载更多
博客详情 1、Markdown 渲染;2、代码高亮、3、膨胀 FloatingActionButton、4、珍藏
评论列表 1、布局;2、评论
账户 1、登录、2、注册

源码

公号「吴小龙同学」回复关键字“AndBlog”获取源码下载链接。

后续更新,这个链接都能够拜访,来,咱们一起持续探讨 Flutter。

如何运行

拿到源码,能够以 Web Server (web) 或 Chrome (web)运行代码,如果你是 MacBook Pro,你还能够以 iPhone 11 Pro Max (mobile)或 macOS (desktop)运行,运行到 Android 手机,开发的时候卡在了 Running Gradle task‘assembleDebug’…或者‘assembleRelease’,这里记录下,这时候个别在下载 Gradle 并配置我的项目,所以可能呈现的问题个别有两种:

报错一:

> Failed to apply plugin [id 'com.android.internal.version-check']
   > Minimum supported Gradle version is 6.1.1. Current version is 5.6.2. If using the gradle wrapper, try editing the distributionUrl in /Users/wuxiaolong/AndroidStudioProjects/flutter_andblog/android/gradle/wrapper/gradle-wrapper.properties to gradle-6.1.1-all.zip

Gradle 目录 windows 个别在 C:\\Users\\ 用户名 \\.gradle\\ 下,macOS 个别在/Users/ 用户名 /.gradle 下。

如果 Android Studio 开发,该门路能够在 ”File | Settings | Build, Execution, Deployment | Build Tools | Gradle” 中批改。

我应用的是“gradle-6.1.1”,能够在官网 https://gradle.org/releases/ 页面下载对应的“complete”安装包,放在 /Users/wuxiaolong/.gradle/wrapper/dists/gradle-6.1.1-all/cfmwm155h49vnt3hynmlrsdst目录下即可。

报错二:

FAILURE: Build failed with an exception.

解决如下:

关上我的项目中 build.gradle 文件

buildscript {
    repositories {//google()
        //jcenter()
        maven {url 'https://maven.aliyun.com/repository/google'}
        maven {url 'https://maven.aliyun.com/repository/jcenter'}
        maven {url 'http://maven.aliyun.com/nexus/content/groups/public'}
        maven {url "http://download.flutter.io"}
    }

    dependencies {classpath 'com.android.tools.build:gradle:4.0.1'}
}

allprojects {
    repositories {//google()
        //jcenter()
        maven {url 'https://maven.aliyun.com/repository/google'}
        maven {url 'https://maven.aliyun.com/repository/jcenter'}
        maven {url 'http://maven.aliyun.com/nexus/content/groups/public'}
        maven {url "http://download.flutter.io"}
    }
}
