Before scraping the data I need first I must choose departure, arrival and date then I must clicked the green buton then I can reach the data I would like to scrape.

How I can perform these actions in website via Flutter. Then I will use these datas in the Flutter app.

I tried to scrape via import http.dart and parser.dart libraries but I couldn’t. I am beginner in coding and Flutter.

You maybe need the dart:html in all app scope , but this file are limited on the web (or You need to do something different on the web than on an Android device!).

you can create 3 file and to handle this mode.

file web.dart :
```
import 'dart:html' as html;

void webScrap() {
  // blablabla webScrap in web
}


String cookie = "";
```
file native.dart :
```
void webScrap() {
  // blablabla webScrap in native
}

String cookie = "";
```
file switch_native_web.dart :
```
import 'native.dart' if (dart.library.html) 'web.dart' as switch_value;

class SwitchNativeWeb {

  static String cookie = switch_value.cookie;

  static void webScrap() {
    switch_value.webScrap();
  }
}
```
But i suggest to you , see this example for web scraping in flutter .
