根因分析

在构造 Uri 对象时使用了格式错误的 URI 字符串（例如缺少方案或双斜杠）。

English

Using a malformed URI string (e.g., missing scheme or double slashes) when constructing a Uri object.

解决方案

  1. Use Uri.file() to create file URIs correctly from a file path.
  2. Validate and sanitize the URI string before parsing with Uri.parse().
  3. Use path_provider to get correct paths and then convert to URI.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Does not address the root cause of missing or malformed scheme (e.g., 'file:///path' vs 'file:///C:/path').

  2. 35% 失败

    Uri.parse requires absolute URIs; relative paths cause assertion errors.

  3. 25% 失败

    Without a scheme, the URI is invalid; the platform may misinterpret the path.
