isolate_current_directory library

Dart's Directory.current can be set to change the current directory, but this is a true global variable shared even between different Isolates.

That makes it almost impossible to write Dart code that requires changing the current working directory while using more than one Isolate, as changes in one Isolate would affect all Isolates.

This library solves that problem by providing a function, withCurrentDirectory(), which effectively changes Directory.current only in the current Isolate.

It relies on IOOverrides to override dart:io's classes behaviour.

Functions

withCurrentDirectory<T>(String directory, FutureOr<T> action()) → FutureOr<T>

Run the given action using the given directory as the working directory.

wrapWithCurrentDirectory<T>(FutureOr<T> fun()) → FutureOr<T> Function()

Wrap an existing function so that the returned function calls withCurrentDirectory around it using Directory.current.path.
