根因分析

解决方案

  1. 使用 permission_handler 包在初始化相机之前请求相机权限。实现权限检查流程,如果权限被永久拒绝,则显示理由对话框。
  2. 将相机初始化包装在 try-catch 块中,优雅地处理 PlatformException,并向用户显示错误消息。

无效尝试

常见但无效的做法:

  1. Adding only the Android permission in AndroidManifest.xml without requesting runtime permission 95% 失败

    On Android 6.0+ and iOS 10+, runtime permission prompt is required; manifest declaration alone is insufficient.

  2. Calling camera plugin directly without checking permission status first 80% 失败

    The plugin throws the exception immediately if permission is denied; no fallback handling is provided.
