Examples #
Performing a GET request :

/// Fetch an object and make it a model type
void getOneDataItemFromEndpoint() async {
SimpleFetch simpleFetch = SimpleFetch();

String apiUrl = 'https://jsonplaceholder.typicode.com/todos/1';

try {
Todo? productsData = await simpleFetch.get<Todo>(
url: apiUrl,
mapper: (json) => Todo?.fromJson(json),
// transformer: (transform) => transform['data'],
);
print(productsData?.toJson());
} on SimpleError catch (exception) {
print(exception.message);
} catch (e) {}
}


/// Fetch a List of object and make it a model type

void getDataFromEndpoint() async {

SimpleFetch simpleFetch = SimpleFetch();

String apiUrl = 'https://jsonplaceholder.typicode.com/todos/';

try {
List<Todo?> allProductsData = await simpleFetch.getList<Todo>(
url: apiUrl,
mapper: (json) => Todo?.fromJson(json),
);

print(allProductsData.map((e) => e?.toJson()).toList());
} on SimpleError catch (exception) {
print(exception.message);
} catch (e) {}
}

Performing a POST request:

/// If the response of your post request is a single item
void postSingleResponse() async {
SimpleFetch simpleFetch = SimpleFetch();

String apiUrl = 'https://jsonplaceholder.typicode.com/todos/1';

try {
Todo? productsData = await simpleFetch.post<Todo>(
url: apiUrl,
data: {'id': 1, 'name': 'hello'},
mapper: (json) => Todo?.fromJson(json),
// transformer: (transform) => transform['data'],
);
print(productsData?.toJson());
} on SimpleError catch (exception) {
print(exception.message);
} catch (e) {}
}

// If the response of your post request is a list of item

void postMultipleResponse() async {

SimpleFetch simpleFetch = SimpleFetch();

String apiUrl = 'https://jsonplaceholder.typicode.com/todos/';

try {
List<Todo?> allProductsData = await simpleFetch.postList<Todo>(
url: apiUrl,
data: {'id': 2, 'name': 'Hiiii'},
mapper: (json) => Todo?.fromJson(json),
);

print(allProductsData.map((e) => e?.toJson()).toList());
} on SimpleError catch (exception) {
print(exception.message);
} catch (e) {}
}

Performing multiple concurrent requests:
response = await Future.wait([request1, request2]);

Transformers #
By default the packages is designed for you to simply retrieve data that is a list or json
Sometimes you may want to remove,add or filter the data that is received before making it an object
The transformer parameter helps you achieve this
{
"data":[
{
"userId": 1,
"id": 1,
"title": "delectus aut autem",
"completed": false
},
{
"userId": 2,
"id": 2,
"title": "User ovier vac",
"completed": true
},
]
}

In this case you may want to return an list so you can do
try {
List<Todo?> allProductsData = await simpleFetch.getList<Todo>(
url: apiUrl,
mapper: (json) => Todo?.fromJson(json),
transformer: (transform) => transform['data'],
);

print(allProductsData.map((e) => e?.toJson()).toList());
} on SimpleError catch (exception) {
print(exception.message);
} catch (e) {}
