http package

Learn the HTTP client with the http package.

The http package

http is Dart's official HTTP client package. The get, post, put, delete functions make simple requests. Each call returns a Future<Response>.

A Response has three main parts: statusCode (int), body (String) and headers (Map). Example: var r = await get(url); print(r.statusCode);.

The package is imported from package:http/http.dart. A URL string is turned into a Uri via Uri.parse.

URLs with Uri.parse

http functions expect the URL as a Uri. Uri.parse('https://example.com/path?q=1') parses a URL string and splits it into structural parts.

Uri parts: .host (example.com), .path (/path), .query (q=1), .scheme (https). Each part can be read individually.

Example: var u = Uri.parse('https://api.example.com/users'); print(u.host); → 'api.example.com'. This is a deterministic way to analyze a URL statically.

Exercise Parse a URL and print it

Inside main add var u = Uri.parse('https://api.example.com/users');. Add print(u.host); and print(u.path);.

Show example solution

void main() {
  var u = Uri.parse('https://api.example.com/users');
  print(u.host);
  print(u.path);
}

Test yourself

What does http.get return?
- String
- int
- Future<Response>
- Stream
Show answer

Future<Response> — get returns a Future<Response> asynchronously.

GET call

var r = await ____(Uri.parse(url));

Show answer

var r = await get(Uri.parse(url));

Match the Uri parts

Domain name
.path
