pathToUri abstract method
Return the URI that should be used to reference the file at the absolute
path, or null if there is no valid way to reference the file in this
converter’s context. The file at that path is not required to exist.
If a containingPath is provided and both the path and containingPath
are within the root of this converter’s context, then the returned URI
will be a relative path. Otherwise, the returned URI will be an absolute
URI.
Throws an ArgumentError if the path is null or is not a valid
absolute file path.
Implementation
Uri? pathToUri(String path, {String? containingPath});
