joinAll method
Joins the given path parts into a single path using the current platform's separator. Example:
p.joinAll(['path', 'to', 'foo']); // -> 'path/to/foo'
If any part ends in a path separator, then a redundant separator will not be added:
p.joinAll(['path/', 'to', 'foo']); // -> 'path/to/foo'
If a part is an absolute path, then anything before that will be ignored:
p.joinAll(['path', '/to', 'foo']); // -> '/to/foo'
For a fixed number of parts, join is usually terser.
Implementation
String joinAll(Iterable<String> parts) => p.context.joinAll(parts);
