You can select the IDE (Integrated Development Environments) you’re most familiar with & install the Flutter & Dart plugins to initiate creating Flutter mobile applications.
Step 2: Comprehending the Widget Tree of Flutter
As we have just talked about, a Flutter app is made up of widgets. Here we will let you know how the widget tree works. Glimpse at the most significant parts of the widget tree in Flutter:
- Widget Hierarchy: In the Flutter framework, you will see a tree of widgets. The top-most widget is called the root widget, however, the other widget is named as its offspring. A widget can have one or more children, which makes a framework with levels.
- Composing Widgets: To make complicated UI layouts, you can put widgets together. You will get lots of pre-made widgets in Flutter, such as Buttons, Containers, Text, Images, and more. By putting together you can make a bespoke layout for the UI. Additionally, You can create your own widgets by simply adding a particular widget to another one or simply putting your own widget to the existing one.
- Widget State: In the Flutter framework, widgets can either have a state or no state. Stateful widgets can be changed however, stateless widgets can’t. Managing the state of widgets is surely a crucial part of making Flutter mobile applications.
Step 3: Making a UI with widgets
Hire dedicated Flutter developer to get the best app development service. Glance at the steps for utilizing widgets to create a User Interface:
- Choose the Right one: Opt the right widgets for UI elements of your app such as input fields, text, photos, buttons, and more.
- Set Up a Hierarchy: As we all know Flutter’s widget comes in a tree structure. So, set up the UI layout of your app so that the root widget can take its position at the top and its children’s widgets are below it. This assistance makes a more organized as well as structured User Interface layout.
- Utilize Layout Widgets: Give your UI elements a great look by simply arranging the layout widgets in the proper way. Complex User Interface layouts can be made with layout widgets such as Stack, Containers, Row, Column, and others. To fit the needs of your mobile app, you can alter the layout of this layout widget by simply utilizing its settings and parameters.
- Handle User Input: You can handle user input in your mobile app with widgets such as GestureDetector, TextField, InkWell, Elevated Button, and more.
Step 4: Managing State of Apps
By managing the states of your app you can make a dynamic, interactive app. Flutter has several ways to control the widgets’ state and the app’s state as a whole. Here are a few significant ideas about how to handle the state of the app in Flutter:
- Stateful Widgets: Stateful widgets are widgets that can change while the mobile application is running. To make a stateful widget in the Flutter framework, you can extend the StatefulWidget class & implement the method createState() to make a mutable state object.
- State Management approaches: Flutter includes various approaches for managing app state, which include BLoC (Business Logic Component), setState(), Provider, Redux, & more. You may control the widgets’ state and the app’s state as a whole in a logical & organized way with these methods.
So, always opt for the right state management method which is required for your app.
Here Reactive programming plays a great role to manage the app state. Flutter also has a framework for reactive programming which is known as RxDart. This allows you to utilize reactive programming patterns such as Streams & Observables in your mobile application. RxDart can be used with other state management approaches to make mobile applications that are reliable as well as scalable.
Step 5: Utilization of the navigation tools
The Flutter framework comes with a built-in navigation tool that makes it easy to control how your mobile application navigates. Here are the crucial things you require to do to deal with navigation in Flutter:
- Handle Navigation Events: Popped, pushed, and replaced are some callbacks for handling navigation events. Utilize these callbacks & events to handle navigation events in your mobile application, such as changing the User Interface, managing the state of the app, and more.
- Navigation Transitions: Flutter has built-in transitions such as Fade Transition, Slide Transition, & more for moving b/w screens. Navigation transitions provide the ultimate touch to your program, enhancing the UX.
