✐ Examples

1 Checking an HTTP URI with a scheme

In this example,

  1. We parse an HTTP URI with a scheme.
  2. We access the `hasScheme` property of the URI.
  3. We print the result, which is true since the URI has a scheme component.

Dart Program

void main() {
  Uri uri1 = Uri.parse('https://example.com');
  print(uri1.hasScheme); // true
}

Output

true

2 Checking a URI without a scheme

In this example,

  1. We parse a URI without a scheme.
  2. We access the `hasScheme` property of the URI.
  3. We print the result, which is false since the URI does not have a scheme component.

Dart Program

void main() {
  Uri uri2 = Uri.parse('example.com');
  print(uri2.hasScheme); // false
}

Output

false
