Top Useful Tips and Untold Secrets Flutter Developers Should Know
Here, I have collected the top tips that will help boost your flutter app development speed, and if you hire flutter developers or get in touch with flutter app development services, these tips may also help!
Use More Packages in Flutter App Development (Helpful When Changing Code Easily)
Well, it may be awkward on the first read, but many Flutter developers have tried this secret and found it helpful. Once the application is published after the whole Flutter app development process, you may get a few comments for changes or feedback. Here, you can look for the packages you used and replace them with your code. It means you will have more control over code with flexibility.
But it all depends on a Flutter app developer's willingness to use many packages at some points. If you require Flutter developers, hire them with this skill, as it saves time.
Use Snippets
Flutter developers generally use things like "StatelessWidget." But it consumes more time during Flutter app development and is unsuitable for project efficiency. Flutter app developers can save time by using snippets.
On VSCode, press F1, find "Snippets, " and find "Configure user snippets." You can find the snippet below.
{
"Main Test Suite Setup": {
"prefix": "testm",
"body": [
"import 'package:flutter_test/flutter_test.dart';",
"",
"void main() {",
" group('${1:${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/g}} -', (){",
"",
" });",
"}"
],
"description": "Main Test Suite Setup"
},
"Test Group Setup": {
"prefix": "testg",
"description": "Creates a Test group with a test",
"body": [
"group('${1} -', () {",
" test('${2}', () {",
"",
" });",
"});",
]
},
"Single Test Setup": {
"prefix": "tests",
"description": "Creates a single test",
"body": [
" test('${1}', () {",
"",
" });",
]
},
}
Set up Linting Early in Flutter App Development
Setting up Linting early impacts the overall Flutter app development. There are different kinds of ways to set up linting. You can set up linting by using the below process-
- In Pubspec.yaml file, add the lint package. You find the package here: Lint package.
- Now, create an ‘’analysis_options.yaml’’ file
- Now, include the line that is sown in the package
By doing this, there are a lot of benefits to flutter app development and for flutter developers too. Try this and comment below.
Use the Provider Package in Flutter App Development
The Provider package is a popular Flutter package that delivers a simple and efficient way to manage the state of your application. With the Provider package, flutter developers can easily manage the state of your application and ensure that changes to the state are reflected in real-time in your UI.
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return ChangeNotifierProvider(
create: (context) => MyModel(),
child: Container(
child: Text("Hello, World!"),
),
);
}
}
Use Git for Version Control
Git is a prevalent form control system that easily tracks changes to your code over time. Also, if you get a Flutter app development company, they do it as primary. With Git, you can quickly revert to a previous version of your code if something goes wrong, and you can collaborate with other developers on the same codebase. To use Git with Flutter, initialize a Git repository in your project directory and use Git commands to manage your code.
Use Custom Widgets
Custom widgets are a way to encapsulate complex UI elements into reusable components. Custom widgets make it easy to reuse UI elements across your application and promote a more organized and maintainable codebase. Extend the "StatefulWidget" or "StatelessWidget" class to create a custom widget.
There are also new updates in Flutter, new release 3.7! Read more: What's new in Flutter 3.7?
Use Build Methods
Build methods are a powerful tool in Flutter that allows you to build UI elements based on your application's state. The build method is called whenever the state of your application changes, and it's responsible for returning the widgets that make up your user interface.
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: Text(widget.text),
),
);
}
Use Dart Streams
Dart streams are a powerful way to handle real-time data in Flutter. Streams provide a way to listen to events as they occur, making it easy to build reactive applications. To use streams, create a StreamController and use the stream property to access the stream.
final StreamController<int> _streamController = StreamController<int>();
...
Stream<int> get stream => _streamController.stream;
Use Hot Reload
Hot reload is a feature in Flutter that allows developers to quickly see changes they make in the code reflected in the running application. It saves a lot of time, as developers don't have to recompile the entire application each time they make changes. To use hot reload, press the "r" key while the app runs in the emulator.
Use the Flutter Outline View
The Flutter Outline view is a handy tool that provides a visual representation of the structure of your Flutter app. This view helps you navigate your code and understand the relationships between widgets and the layout of your app. Go to View -> Flutter Outline in Android Studio to open the Flutter Outline view.
Use Named Routes
When building an application with multiple pages, it's often helpful to use named routes. Named routes make it easier to navigate between pages and allow for a more organized and maintainable codebase. To use designated routes, specify a name for each route when you push a new page onto the Navigator.
Navigator.pushNamed(context, '/home');
Use Code Generators
Code generators are a powerful tool that can help to automate the process of writing repetitive code. Flutter provides many code generators, such as flutter create, flutter pub run build_runner, and more, that can help streamline the development process and reduce the manual coding required.
flutter pub run build_runner build
Use HTTP Networking Libraries
HTTP networking is a common requirement for many Flutter apps. Many popular HTTP networking libraries are available to make it easier to work with HTTP in Flutter, including "http" and "dio." These libraries provide a simple and efficient way to make HTTP requests and handle responses.
Future<http.Response> getData() async {
http.Response response = await http.get("https://www.example.com");
return response;
}
Use Dependency Injection
Dependency Injection is a commanding design that makes managing dependencies in your Flutter apps easy. Dependency injection can make your code more modular and maintainable by allowing you to swap out dependencies quickly. Several popular dependency injection libraries are available for Flutter, including "get_it" and "inject."
class MyService {
String greeting() => "Hello, World!";
}
class MyWidget extends StatelessWidget {
final MyService _myService;
MyWidget({@required MyService myService}) : _myService = myService;
@override
Widget build(BuildContext context) {
return Text(_myService.greeting());
}
}
Use Dart Mixins
Dart Mixins are a powerful feature of the Dart programming language that allows you to reuse code between classes. Mixins can be used in Flutter to help you share code between widgets and reduce the amount of redundant code in your app.
class MyMixin {
String sayHello() => "Hello from MyMixin";
}
class MyWidget extends StatelessWidget with MyMixin {
@override
Widget build(BuildContext context) {
return Text(sayHello());
}
}
Use State Management Libraries
State management is a critical aspect of building Flutter apps, and it can be challenging to manage a clean and maintainable state. Several popular state management libraries are available to make it easier to manage the condition in Flutter, including Bloc, Redux, and Provider. These libraries provide a simple and efficient way to manage the state of your apps and keep your code organized and maintainable.
class MyBloc {
final _counter = BehaviorSubject<int>(seedValue: 0);
Observable<int> get counter => _counter.stream;
void increment() {
_counter.sink.add(_counter.value + 1);
}
void dispose() {
_counter.close();
}
}
final myBloc = MyBloc();
class MyWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return StreamBuilder<int>(
stream: myBloc.counter,
builder: (context, snapshot) {
return Text("Counter: ${snapshot.data}");
},
);
}
}
Use Flutter Inspector
The Flutter Inspector is a powerful tool built into the Flutter development environment to help you debug and optimize your Flutter apps. The Flutter Inspector provides a visual representation of your widget tree and detailed information about each and its properties. Using the Flutter Inspector, you can quickly identify and resolve issues in your app and improve its performance.
You can reach a flutter app development company if you need a solution in complex situations.
Use Flutter CLI Tools
The Flutter CLI provides several powerful tools for managing and optimizing your Flutter projects. These tools can help you manage dependencies, run tests, analyze your code, and more. Using the Flutter CLI tools, you can streamline your development process and improve the quality and performance of your Flutter apps.
flutter run
flutter test
flutter analyze
