json_to_form_with_theme 4.1.10

A simple library to convert Json to Form, fully customized and dynamic.

This library aims to help developer get started quickly and create a form made out of json.

Features

The JsonForm can be updated both from the user interaction but can also be notified from outside (check the example for the stream). You can also get the Json back.

Usage

You can declare a Json as:

  final Map<String, dynamic> json = {
    "widgets": [
      {
        "id": "1",
        "name": "Toggle",
        "type": "toggle",
        "values": ["On", "Off"],
        "default_value": "0",
        "chosen_value": 1
      },
      {
        "id": "2",
        "name": "Static text",
        "type": "static_text",
        "chosen_value": "value",
        "description": "(description..)",
      },
      {
        "id": "3",
        "name": "Edit text",
        "type": "edit_text",
        "chosen_value": "edit value",
        "description": "(edit description..)",
      },
      {"type": "header", "name": "Header", "id": "99"},
      {
        "id": "4",
        "name": "Drop down",
        "type": "drop_down",
        "values": ["Low-Intermediate", "Medium", "High"],
        "chosen_value": "Low-Intermediate"
      }
    ]
  };

And easily use the basic Theme (or edit it)

 @override
 Widget build(BuildContext context) {
  return Sizer(
    builder: (BuildContext context, Orientation orientation, DeviceType deviceType) {
      return Scaffold(
        appBar: AppBar(
          title: const Text('Floating Action Button'),
        ),
        body: RefreshIndicator(
          onRefresh: _refresh,
          child: JsonFormWithThemeBuilder(
              jsonWidgets: json)
              .setDateBuilderMethod(dateBuilder)
              .registerComponent(DropDownParser2Creator())
              .setStreamUpdates(onValueChangeStream)
              .setOnValueChanged((String d, dynamic s) async {
            print("Update id $d to value $s");
            await Future.delayed(const Duration(seconds: 1));
            return Future.value(true);
          })
              .setTheme(const DefaultTheme()).build(),
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: () {
            counter++;
            if (counter % 4 == 1) {
              toggle++;
              _onUserController.add({}..["1"] = toggleList[toggle % 2]); // toggle
            }
            if (counter % 4 == 2) {
              _onUserController.add({}..["2"] = "updated" + Random().nextInt(10).toString()); // toggle
            }
            if (counter % 4 == 3) {
              _onUserController.add({}..["3"] = "Val" + Random().nextInt(100000).toString()); // toggle
            }
            if (counter % 4 == 0) {
              _onUserController.add({}..["4"] = list[toggle % 2]); // toggle
            }
          },
          child: const Icon(Icons.navigation),
          backgroundColor: Colors.green,
        ),
      );
    },
  );
}
