{
"status": "error",
"msg": "Please ensure all fields are filled out properly",
"error": {
"device_token": [
"The device token field is mandatory.",
]
"mobile_number": [
"The mobile number cannot be left blank."
]
}
}
This is the JSON response I received. I need help on how to handle dynamic error objects.
In order to retrieve the necessary data from your JSON content, it is important to store the content in a variable and access the required information accordingly.
Moreover, it's essential to include a comma "," after the key "device_token".
let jsonData = {
"status": "error",
"message": "Please ensure all fields are filled",
"error": {
"device_token": [
"The device token field must be provided."
],
"mobile_number": [
"The mobile number field must be provided."
]
}
};
const deviceTokenValue = (jsonData["error"] as Map)["device_token"][0];
const mobileNumberValue = (jsonData["error"] as Map)["mobile_number"][0];
console.log(deviceTokenValue);
console.log(mobileNumberValue);
For a comprehensive understanding of JSON and Serialization in the context of Flutter, I suggest diving into the documentation provided on Flutter's official website.
In order to tackle this issue, I found a fantastic tool called json_seializable. It proved to be the perfect solution for my needs. This package allows you to effortlessly annotate your models and automatically generate all the necessary methods. Remarkably, the official flutter documentation highly recommends using it. Moreover, ensuring that your variables are properly typed and leveraging the sheer power of the Dart compiler is absolutely crucial.
