utility_flutter

This package provides a comprehensive utility to handle common HTTP and shared preferences operations with ease. Built around the http and shared_preferences package, it integrates seamlessly with Flutter and Dart applications, offering features like setting default headers, configuring request timeouts, and delivering standardized error responses and storing smale variables in device.

🌟 Features

HttpUtils

• Simplified HTTP Requests: Perform GET, POST, PUT, and DELETE operations with just a few lines of code.

• Consistent Base URL: Define a base URL once and forget about repeating it for every request.

• Default Headers: Easily set default headers that automatically accompany every HTTP request.

• Timeouts: A default timeout duration ensures your requests don't hang indefinitely.

• Standardized Errors: Understand and handle HTTP errors better with standardized error responses.

• Create an instance of HttpUtils: Create an instance of the HttpUtils class by providing the baseUrl for your API. You can also specify optional parameters like defaultHeaders and timeoutDuration. For example:

final httpUtils = HttpUtils('https://api.example.com', defaultHeaders: {
  'Authorization': 'Bearer your_token_here',
});

• GET Request:

try {
  final response = await httpUtils.get('/endpoint');
  // Handle the response
} catch (e) {
  // Handle errors
}

• POST Request:

try {
  final body = {'key': 'value'};
  final response = await httpUtils.post('/endpoint', body: body);
  // Handle the response
} catch (e) {
  // Handle errors
}

• PUT Request:

try {
  final body = {'key': 'value'};
  final response = await httpUtils.put('/endpoint', body: body);
  // Handle the response
} catch (e) {
  // Handle errors
}

• DELETE Request:

try {
  final response = await httpUtils.delete('/endpoint');
  // Handle the response
} catch (e) {
  // Handle errors
}

• if your API have no need of defaultHeaders or headers, you no need to initializes this .

PreferencesUtils

• Initialize the PreferencesUtils instance : use in your project .

void main() async {
  WidgetsFlutterBinding.ensureInitialized(); // Required to use async methods in the main function.
  final preferences = PreferencesUtils();
  await preferences.init();

  runApp(MyApp());
}

• Initialize the PreferencesUtils instance

// Get a PreferencesUtils instance.
final preferences = PreferencesUtils();

// Storing data:
await preferences.setBool('isDarkMode', true);
await preferences.setInt('userAge', 25);
await preferences.setDouble('userHeight', 175.5);
await preferences.setString('username', 'navneet');

• isDarkMode, userAge, userHeight, username these are key using this you can get stored data from your device.

// Retrieving data:
bool isDarkMode = preferences.getBool('isDarkMode');
int userAge = preferences.getInt('userAge');
double userHeight = preferences.getDouble('userHeight');
String username = preferences.getString('username');

// Clearing preferences:
preferences.clear();
