Flutter调用video_editor_sdk打开编辑器崩溃：ExceptionInInitializerError

从相册选取视频后，调用video_editor_sdk插件的编辑功能时应用直接崩溃，调用代码如下：

final result = await VESDK.openEditor(
        Video(path)
);

环境信息 #

• 使用插件：video_editor_sdk
• Flutter SDK版本：3.7.7
• 已按照插件官方README完成项目配置

错误核心是Gradle配置缺失导致SDK自动生成类无法被找到，按以下步骤修复：

1. 检查并升级Gradle插件版本
   修改项目根目录build.gradle中的Gradle插件版本至7.0及以上：

   dependencies {
       classpath 'com.android.tools.build:gradle:7.4.2'
       // 其他依赖项保留
   }
   

2. 启用数据绑定
   在app/build.gradle的android代码块中添加数据绑定配置：

   android {
       // 其他现有配置
       buildFeatures {
           dataBinding true
       }
   }
   

3. 清理重建项目

   • 执行终端命令：flutter clean && flutter pub get
   • 重启Android Studio，依次执行Build -> Clean Project和Build -> Rebuild Project

4. 添加混淆豁免规则
   若项目开启混淆，在proguard-rules.pro中添加：

   -keep class ly.img.android.pesdk.** { *; }
   -keep class ly.img.flutter.video_editor_sdk.** { *; }
   

5. 验证Maven仓库配置
   确认项目根目录build.gradle的allprojects -> repositories中包含以下仓库：

   allprojects {
       repositories {
           // 其他现有仓库
           maven { url "https://artifactory.img.ly/artifactory/imgly" }
           mavenCentral()
       }
   }
