No matter how beautiful your app's UI is, it will not matter unless it is fully functional to access real-time data. To go beyond just Lorem ipsum you need to add the right content to support it along with the interaction that enables users to fetch and add data to the application.
There are multiple ways to make data accessible on the front-end but the most common and secure way is accessing data through API integration. Integrating APIs to your application enables smooth communication between the frontend UI and server.
In this article, we will learn how to integrate API into the Flutter application using DhiWise, but before that, understand what REST API is and how it works.
So let's get started!
An API is the set of definitions and protocols for building and integrating the application software. You can put it Simply as a contract between an information provider and the user.
For example, the API design for movie ticket booking could specify that users need to supply the Theater name, movie name, show time, and the number of seats. And the replay body should have the available seats for the requested show.
In general, API acts as a mediator between the end user and backend resources and services. In fact, it is the most secure and fastest way to make applications communicate while having full control over app services and data.
REST (Representational State Transfer) API or the web API conforms to the constraints of REST architectural style and allows app interactions with the RESTful web services.
REST API uses simple HTTP calls to communicate with JSON data. A user application can make GET, POST, PUT or DELETE HTTP requests to a database and send results for the query request in the response database. The result can be in JSON, HTML, or XML, which is then parsed into the proper model class to use in the app.
In general, you will go through the following steps for integrating an API into the Flutter application.
Moreover, while integrating APIs you need to consider the web standards and conventions.
DhiWise is a modern LowCode and ProCode programming platform for developers that supports multiple technologies for app development including Flutter. It offers a variety of features to make the process of app development efficient, and effortless. And one of them is API integration.
DhiWise simplifies REST API integration in Flutter in the following ways,
DhiWise allows developers to integrate API on the screen, widget, or view components.
To integrate an API on screen, you can choose any screen from the app screen list or select the Configure option for a particular screen, where you want to set up an API.
To integrate API on the widget, add the onClick property for setting up action and then choose the API integration from the action list.
Once you choose the API integration action, it will ask you to submit the correct function name for the API integration which will be generated for the screen code.
To add an API on the view component bind the selected view widget or lifecycle method from the list of APIs added.
Moreover, with DhiWise you can also handle the request and response to the server.
You can set the APIs Header, Parameters, and the Body from the Handle request area. Also, you can change the existing values if necessary.
Next, you need to bind the request key with any of the below-supported types to send data to the API request.
Finally, to display the response values coming from the APIs with the views of your screen, select the key from the response, and select the View you want to bind from the right side.
If you want to display the data in the List/Grid or Slider from the API response, bind the response array with the List/Grid or Slider view. And while handling the response data, save them to preferences by selecting the response key and giving it the desired name.
After the API call is placed you need to choose the action based on the success or failure of the method. You can select actions such as API integration, Navigation, and Show Alert Dialog, Toast, or Snackbar.
And once everything is done, click to save changes.
So, this is all about API integration in the Flutter app with DhiWise.
In the article, you have learned about the REST API, the way it works, and how DhiWise speeds up REST API integration in the Flutter application through the visual interface.
