createPath static method
Allows for the easy creation of a path string.
createPath(
localDir: LocalDir.tempDir,
subPath: "/images",
) == "/path/to/tmp/images"
Throws a FormatException if subPath
is not a valid path. Below are
some invalid paths:
subPath: "@image" => throws FormatException
subPath: "../image" => throws FormatException
subPath: "~" => throws FormatException
subPath: "" => throws FormatException
Implementation
static Future<String> createPath({
required LocalDir localDir,
required String subPath,
}) async {
final String localDirPath =
"${await fetchPath(localDir)}${Platform.pathSeparator}";
final String subPathSterile = sterilizePath(subPath);
// Check for valid sub-path.
if (subPathSterile.isEmpty) {
throw FormatException("$subPath is not a valid sub-path!");
}
return "$localDirPath$subPathSterile";
}
