# FileSystemException constructor Null safety

const FileSystemException(

1. [String message = "",
2. String? path = "",
3. OSError? osError]

)

Creates a new FileSystemException with an optional error message `message`, optional file system path `path` and optional OS error `osError`.

## Implementation

    @pragma("vm:entry-point")
    const FileSystemException([this.message = "", this.path = "", this.osError]);
