NetworkUtils Class #
The NetworkUtils class is used to perform HTTP requests. It requires a URL, a caller identifier, and a callback object that implements the NetworkResponce interface.
GET Request
NetworkUtils task = NetworkUtils("https://example.com/api", 'getData', this);
await task.get();

POST Request

await task.post(data: {'key': 'value'});

PUT Request
NetworkUtils task = NetworkUtils("https://example.com/api/1", 'putData', this);
await task.put(data: {'key': 'newValue'});
copied to clipboard
DELETE Request
NetworkUtils task = NetworkUtils("https://example.com/api/1", 'deleteData', this);
await task.delete();

Multipart POST Request
NetworkUtils task = NetworkUtils("https://example.com/upload", 'uploadFile', this);
await task.multipartPost(
data: {'description': 'file upload'},
filePath: '/path/to/file.jpg'
);

NetworkResponce Interface #
The NetworkResponce interface defines two methods:

onTaskComplete(String result, String caller): Called when a request completes successfully.
onTaskError(String error, String caller): Called when a request fails.

Implement this interface in your class to handle responses and errors.
