-
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。
-
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:
-
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.
-
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.
