How to use a variable inside a URL in FLUTTER-CodePudding

Why this is working ?

final response = await http.get(Uri.parse("http..../?page=2"),

But this is not !

int p = 2;
String page = p.toString();
final response = await http.get(Uri.parse("http..../?page=" p),

CodePudding user response：

Do it like this

final response = await http.get(Uri.parse("http..../?page=$p"),

CodePudding user response：

For this purpose Uri.https has a Map<String, dynamic>? queryParameters, property.

You can use it this way:

  final p = 2;
  final parameters = <String, String>{
     'page': p.toString(),
    };
  
  
  final uri = Uri.http(
    'http....com',
    '/',
    parameters,
  );
  final response = await httpClient.get(uri);
