现在 9.5.6 移除了 QuillProvider，直接使用工具栏和编辑器即可，具体参看[富文本编辑组件](lib/views/diary/diary_modify_rich_text.dart)的相关代码。

之前编辑器 QuillEditor 有 readOnly 属性，现在是在 ` _controller.readOnly = !isEditing;` 设定了，所以在改动是否可以编辑的地方，修改控制器的只读属性。

#### flutter 升级到 3.22 后打包 apk 的体积增加很多

我看 0.0.1-beta 的时候，只有不到 18M，但升级到 3.22 后打包就到了 将近 37M。使用以下命令查看:

```sh
flutter build apk --target-platform android-arm64 --analyze-size
```

得到结果:

A summary of your APK analysis can be found at: /home/david/.flutter-devtools/apk-code-size-analysis_08.json

To analyze your app size in Dart DevTools, run the following command:
dart devtools --appSizeBase=apk-code-size-analysis_08.json
```

</details>

得到了类似`/home/david/.flutter-devtools/apk-code-size-analysis_08.json`的分析文件后，假如使用的是 VSCode，就在“查看”->“命令面板”，输入"devtool"，找到“Flutter: Open DevTools”，找到打开开发工具的位置。

我是在网页打开，然后点击网页上方的“App Size”按钮，把刚刚的`apk-code-size-analysis_08.json`打开，分析 apk 的体积问题。

而这个体积增加的问题，参看 stackoverflow 的 [Flutter App Size İncrease Too much after Updating Dependencies](https://stackoverflow.com/questions/78550965/flutter-app-size-%C4%B0ncrease-too-much-after-updating-dependencies) 问题。

**在`android/app/build.gradle` 的`android`对应配置中添加以下代码(没有就新增)**：

```gradle
android {
packagingOptions {
jniLibs {
useLegacyPackaging true
}
}
}
```

此时 3 个体积的变化为:

- 0.0.1.bata：17.7M
- 升级到 flutter 3.22 默认： 36.6M
- 升级到 flutter 3.22 打包压缩的原生库：19.7M
