Как отправить массив JSON, заполненный данными из Flutter, в API, созданный с помощью php ⇐ Php

[Anonymous]

В настоящее время я работаю над проектом и столкнулся с проблемой отправки массива JSON в PHP API.
Вот код, который я написал для приложения flutter:

class AddDeviceFormScreen extends StatelessWidget {
final TextEditingController deviceNameController = TextEditingController();
final TextEditingController deviceDescriptionController = TextEditingController();
final TextEditingController deviceClusterController = TextEditingController();
final TextEditingController deviceGeolocation1Controller = TextEditingController();
final TextEditingController deviceGeolocation2Controller = TextEditingController();
final TextEditingController sensorWater1LevelController = TextEditingController();
final TextEditingController sensorWater2LevelController = TextEditingController();
final TextEditingController sensorWater3LevelController = TextEditingController();
final TextEditingController sensorLevel1AlertLevelController = TextEditingController();
final TextEditingController deviceWiFiNameController = TextEditingController();
final TextEditingController deviceWiFiPasswordController = TextEditingController();
final TextEditingController deviceMACController = TextEditingController();
