使用flutter_launcher_icons自动生成Flutter应用程序图标

I’ve been working on a Flutter application for the better half of this year, and as we get closer to release, I realized I hadn’t set an app icon yet. I initially went ahead and set my icons with Xcode and Android Studio, but after finding the `flutter_launcher_icons` plugin - I’ll never need to do this manually again!

今年下半年，我一直在开发Flutter应用程序，随着我们发布的临近，我意识到我尚未设置应用程序图标。 我最初继续使用Xcode和Android Studio设置图标，但是找到`flutter_launcher_icons`插件后-我再也不需要手动执行此操作！

To see how this works yourself, boot up your current Flutter project or follow along with the demonstration below.

要了解自己的工作方式，请启动当前的Flutter项目或按照下面的演示进行操作。

## 创建一个新的Flutter项目 **(**Creating a new Flutter project**)** ##

As always, we’ll start off by setting up a new project and adding the plugin:

与往常一样，我们将从建立一个新项目并添加插件开始：

# New Flutter project
    $ flutter create f_icons
    
    # Open this up inside of VS Code
    $ cd f_icons && code .

## 添加Flutter Launcher Icons插件 **(**Adding the Flutter Launcher Icons Plugin**)** ##

Head over to your `pubspec.yaml` and add the following plugin to our `dev_dependencies`:

转到您的`pubspec.yaml`并将以下插件添加到我们的`dev_dependencies` ：

dev_dependencies:
      flutter_launcher_icons: ^0.7.4

We can then ensure we have the latest packages in our project by running:

然后，我们可以通过运行以下命令来确保我们的项目中拥有最新的软件包：

$ flutter pub get

## 应用徽标 **(**App Logo**)** ##

Now that we’ve got a Flutter project, we’ll need a logo to set as an icon. Here’s one that we can use, imagine it’s a camera application:

现在我们有了Flutter项目，我们需要一个徽标来设置为图标。 这是我们可以使用的，想象它是一个相机应用程序：

Place your icon inside of your `assets/images/icon.png` folder, or a similar folder of your choosing. Then, inside of `pubspec.yaml`, we’ll need to provide the `flutter_icons` configuration option:

将图标放置在`assets/images/icon.png`文件夹或您选择的类似文件夹中。 然后，在`pubspec.yaml`内部，我们需要提供`flutter_icons`配置选项：

flutter_icons:
      image_path: 'assets/images/icon.png'
      android: true
      ios: true

This will generate application icons for Android and iOS using the one specified. We can also configure this deeper by providing an `image_path` per platform if we wanted to have a separate icon. Here’s how:

这将使用指定的图标为Android 和 iOS生成应用程序图标。 如果我们想要一个单独的图标，我们还可以通过在每个平台上提供一个`image_path`更深入的配置。 这是如何做：

flutter_icons:
      image_path_ios: 'assets/images/heal.png'
      image_path_android: 'assets/images/heal.png'
      android: true
      ios: true

With this in mind, let’s go ahead and generate the icons!

考虑到这一点，让我们继续生成图标！

## 运行构建脚本 **(**Run the Build Script**)** ##

Inside of your terminal, run the following build script:

在终端内部，运行以下构建脚本：

$ flutter pub run flutter_launcher_icons:main

If everything worked correctly, we should see the following result:

如果一切正常，我们应该看到以下结果：

Android minSdkVersion = 16
    Creating default icons Android
    Overwriting the default Android launcher icon with a new icon
    Overwriting default iOS launcher icon with new icon

## 结果 **(**Results**)** ##

Let’s run our application on a device or emulator. We should be able to see our awesome new icon!

让我们在设备或仿真器上运行我们的应用程序。 我们应该能够看到我们很棒的新图标！
