Getting Started

The simplest example is to use the default avatar and default parameters: 最简单的例子是使用默认头像及默认参数：

const Avatar()

The effect of this code is as follows: 其运行效果如下：

你也可以指定一些头像参数，但是如果你指定一个错误的头像地址，将自动地使用默认头像，例如：

Avatar(
  size: 100,
  backgroundColor: Colors.indigo,
  borderRadius: 40,
  padding: EdgeInsets.all(20),
  image: 'https://example.com/avatar.jpg',
),

The effect of this code is as follows: 其运行效果如下：

如果要可以设置一个真实的网络图片URL作为头像，则它必须以http开头，例如：

const Avatar(
  size: 200,
  borderRadius: 100,
  image:
      'https://profile-avatar.csdnimg.cn/bb869bb0b79b48209c6206043890c985_qq_28550263.jpg',
),

The effect of this code is as follows: 其运行效果如下：

Oh, this is me. An active user of the open source community! 哦，这就是我了。一个开源社区的活跃用户！

Actually, you can also use animation, which doesn't matter: 其实你还可以使用动图，这没关系的：

const Avatar(
  size: 200,
  margin: EdgeInsets.all(6),
  borderRadius: 60,
  image:
      'https://github.githubassets.com/images/mona-loading-dimmed.gif',
),

The effect of this code is as follows: 其运行效果如下：

If the avatar itself has a transparent background, you can see the default background color or background picture. Also, you can add an outer border for your avatar, such as: 如果头像本身是透明背景的，可以看到默认背景色 或 背景图片。并且，你还可以为你的头像添加外边框，例如：

Avatar(
  size: 200,
  padding: const EdgeInsets.all(10),
  margin: const EdgeInsets.all(10),
  borderRadius: 80,
  backgroundColor: Colors.white, // 如不设置，则为灰色
  // 可以为你的头像添加边框
  border: Border.all(
    color: const Color.fromARGB(255, 0, 0, 0),
    width: 6.0,
    style: BorderStyle.solid,
    strokeAlign: BorderSide.strokeAlignInside,
  ),
  image:
      'https://gitee.com/jacklee1995/example-pictures/raw/master/asian/asian-girl-avatar.png',
),

The effect of this code is as follows: 其运行效果如下：

Next is an example of using a network picture as a background picture, which will cover the background color effect: 接下来是一个使用网络图片作为背景图的例子，这个网络图片将覆盖背景颜色效果：

const Avatar(
  size: 200,
  margin: EdgeInsets.all(10),
  borderRadius: 80,
  backgroundImage:
      'https://gitee.com/jacklee1995/example-pictures/raw/master/scenery/jonathanvasquez8950_scenery_2f6031d1-c4fe-41d7-8abf-d1c9c40d9981.png',
  image:
      'https://gitee.com/jacklee1995/example-pictures/raw/master/asian/asian-girl-avatar.png',
),

The effect of this code is as follows: 其运行效果如下：

Now, let's explore some special effects - Avatar out of the box.

The Avatar class provides an intermediate layer border property called interlayerBorder. Using this property instead of the border property will help you achieve the effect of characters coming out of the frame. Here's an example code: 下面我们玩一点特效——人物出框。 Avatar 类提供了一个中间层边框属性 interlayerBorder，通过该属性而不是 border 属性设置的边框将帮助你完成人物出框的效果。示例代码如下：

Avatar(
  size: 200,
  interlayerBorder: Border.all(
    color: const Color.fromARGB(255, 255, 251, 3),
    width: 20.0,
    style: BorderStyle.solid,
    strokeAlign: BorderSide.strokeAlignInside,
  ),
  // margin: const EdgeInsets.all(6),
  borderRadius: 100,
  backgroundImage:
      'https://gitee.com/jacklee1995/example-pictures/raw/master/scenery/jonathanvasquez8950_scenery_2f6031d1-c4fe-41d7-8abf-d1c9c40d9981.png',
  image: 'assets/asian-boy-avatar.png', // 也可以使用本地图片资源
)

The effect of this code is as follows: 其效运行果如下：

文字头像（Text Avatar）

Since v2.0.0, a new layer has been added to display text, but the textMode must be turned on with the textmode parameter. If no text is specified, it will be displayed as "?" No, otherwise it is displayed as the text specified by using the text parameter.

从 v2.0.0 开始，添加了新的图层用于显示文字，但是必须使用 textMode 参数开启文字模式。如果没有指定文本，将显示为“?”号，否则显示为使用 text 参数所指定的文本。

examples: 例如：

const Avatar(textMode: true),

The effect of this code is as follows: 效果为：

const Avatar(
  textMode: true, // 文字模式必须启用此参数
  text: 'Lee', // 默认仅仅使用一个字符
),

The effect of this code is as follows: 效果为：

If the text consists of more than one word, you need to specify the number of words through the wordsCount parameter to display more than one character: 如果文本由多个单词构成，需要通过 wordsCount 参数指定单词的数量以显示多个字符：

const Avatar(
  textMode: true,
  text: 'Jun Cai',
  borderRadius: 40,
  wordsCount: 2, // 单词数量，用于显示多个单词的首字符
),

The effect of this code is as follows: 效果为：

Let's enjoy it!~ 尽情探索吧！~
