解决方案 #

• 添加JitPack仓库：报错显示依赖托管在JitPack，但当前项目仓库配置未包含该源。修改build.gradle中的allprojects部分，新增JitPack仓库：

  allprojects {
      repositories {
          google()
          mavenCentral()
          maven { url 'https://jitpack.io' } // 添加该行
      }
  }
  

• 清理缓存重试：若添加仓库后仍无法拉取依赖，执行以下步骤清除缓存：

  1. 运行flutter clean清除Flutter项目缓存
  2. 删除Android目录下的.gradle文件夹
  3. 重新执行flutter build apk --release

• 切换插件稳定版本：当前依赖的是awesome_notifications引入的开发版依赖，稳定性不足。可在pubspec.yaml中指定该插件的稳定版本，避免自动拉取开发版依赖。
