1 Resolving a relative path

In this example,

  1. We create a base Uri object baseUri with the value 'https://example.com/path/'.
  2. We create a reference Uri object referenceUri with the value 'doc.html'.
  3. We use the resolveUri method to resolve the reference URI relative to the base URI.
  4. We then print the result to standard output.

Dart Program

void main() {
  Uri baseUri = Uri.parse('https://example.com/path/');
  Uri referenceUri = Uri.parse('doc.html');
  Uri resolvedUri = baseUri.resolveUri(referenceUri);
  print('Resolved URI: $resolvedUri');
}

Output

Resolved URI: https://example.com/path/doc.html

2 Resolving a relative path with parent directory navigation

In this example,

  1. We create a base Uri object baseUri with the value 'https://example.com/path/file.txt'.
  2. We create a reference Uri object referenceUri with the value '../images/image.jpg'.
  3. We use the resolveUri method to resolve the reference URI relative to the base URI.
  4. We then print the result to standard output.

Dart Program

void main() {
  Uri baseUri = Uri.parse('https://example.com/path/file.txt');
  Uri referenceUri = Uri.parse('../images/image.jpg');
  Uri resolvedUri = baseUri.resolveUri(referenceUri);
