✐ Examples

1 URI with fragment part

In this example,

  1. We create a Uri object uri1 by parsing the string 'http://example.com/path#fragment'.
  2. We use the hasFragment property to check if the URI has a fragment part.
  3. We then print the result to standard output.

Dart Program

void main() {
  Uri uri1 = Uri.parse('http://example.com/path#fragment');
  bool hasFrag1 = uri1.hasFragment;
  print('URI 1 has fragment: $hasFrag1');
}

Output

URI 1 has fragment: true

2 URI without fragment part

In this example,

  1. We create a Uri object uri2 by parsing the string 'mailto:user@example.com'.
  2. We use the hasFragment property to check if the URI has a fragment part.
  3. We then print the result to standard output.

Dart Program

void main() {
  Uri uri2 = Uri.parse('mailto:user@example.com');
  bool hasFrag2 = uri2.hasFragment;
  print('URI 2 has fragment: $hasFrag2');
}

Output

URI 2 has fragment: false

3 URI without scheme

In this example,

  1. We create a Uri object uri3 by parsing the string 'file:///path/to/file'.
  2. We use the hasFragment property to check if the URI has a fragment part.
  3. We then print the result to standard output.

Dart Program

void main() {
  Uri uri3 = Uri.parse('file:///path/to/file');
  bool hasFrag3 = uri3.hasFragment;
  print('URI 3 has fragment: $hasFrag3');
}

Output

URI 3 has fragment: false
