flutter passing multiple data with getx

Question

I want to Pass multiple data from one screen to another screen with Get package.

Get.to(Second(), arguments: ["First data", "Second data"]);

Solution 1

Step: 1 : Sending data

Get.to(Second(), arguments: ["First data", "Second data"]);

Step: 2 : Get data From first screen

var data = Get.arguments;

Solution 2

I found this solution.

First screen

 Get.to(Second(), arguments: ["First data", "Second data"]);

Second screen

Declare variable (list)

    var one = Get.arguments;

Set data

Column(
        mainAxisAlignment: MainAxisAlignment.center,
        children: [
          Text("${one[0]}"), // first element set here
          Text("${one[1]}"), // second element set here
        ],
      )

Solution 3

If you need to pass data with key and value in getx then try this

First Screen

Get.to(() => SecondScreen(), arguments: [
    {"first": 'First data'},
    {"second": 'Second data'}
]);

Second screen

class SecondScreenController extends GetxController {
  dynamic argumentData = Get.arguments;

  @override
  void onInit() {
    print(argumentData[0]['first']);
    print(argumentData[1]['second']);
    super.onInit();
  }
}

Get.back() result

Get.to(() => SecondScreen(), arguments: [
   {"first": 'First data'},
   {"second": 'Second data'}
]).then((result) {
    if (result[0]["backValue"] == "one") {
        print("Result is coming");
    }
});

Get.back(result: [
    {"backValue": "one"}
]);

I am passing data like: onPressed: () => Get.to(() => GendersPage(), arguments: {"FOR_SELECTION", true}), but when I try to access argument as map, I get an error. final Map<String, bool>? args = Get.arguments; bool get forSelection => args!["FOR_SELECTION"]!;

What about the case of ''Get.back();'' To send data back? Any ideas? I'm struggling with it hardly

Is there a way to use onGenerateRoute function, like in the documentation flutter.dev/docs/cookbook/navigation/navigate-with-arguments‌​, but using getx?
