There is no doubt that flutter is one of the best frameworks for developing the user interface of cross-platform websites. It comes with inbuilt widgets and library functions and allows developers to work on various elements, including positioning, animation, movement, and several other aspects. In fact, and user interface designed with the help of flutter is more functional, efficient, and productive. Apart from this, flutter has well-recorded documentation, making it easy for professionals to work on various elements of the UI and define them in innovative ways.
One such process that flutter can facilitate is creating a fading animation in the images to be published on the website. From the name itself, you can understand that the animation will cause the image to fade after a specific time defined by the user side. Therefore, either developer can introduce this animation during the image’s entry or exit, just like in a presentation. However, writing the codes for fading the image takes work. There are several ways to write the best quality code for your project. For that, you need to consult and hire flutter team for the development and implementation of placeholder effect in your project. It is the easiest option for working remotely and dedicatedly for your project. There are various elements and aspects to consider before writing the codes or creating the widgets.
The following article will help you to understand how flutter Developers can write the codes for fading in the images using flutter.
What is the use of fading in animation on the website UI?
Before moving further into the details of using flutter to fade in the images, it will be much better if we understand the applications of this particular animation in the UI. The question is entirely justified because there are so many different animations one can incorporate into the interface. So, where does this fade-in animation fit? To answer this question, we have listed specific scenarios explaining how the fading animation can make the user interface look more visually stunning and appealing to the audience.
- When you want to add a slider on the website but in a way that the transition between one slide to another can be well defined using an animation, fading in sounds is the perfect option. This way, you can connect the content of one slide with another and establish a more inquisitive user interface.
- Sometimes, you can also work on fading images at the beginning of any presentation, website sections, etc. This will help you to entice your target audience and move on to the actual content without creating any noticeable gap.
- We must acknowledge that fading image animation is perhaps one of the best ways to enhance the visual appeal of the UI and make it more intuitive.
Before writing the codes for fading animation of images, what should you know?
Although the code for creating a fade-in animation for the image to be displayed on the screen is quite simple, you need to understand a couple of terms and elements with which you will write the codes. In the below section, we have defined a couple of terms you will encounter while reading more about how to create the animation.
1.Placeholder is a property you can use in flutter whenever you have to add animations to the target image. It can be considered a buffer memory storage where a copy of the image is stored and displayed at the very beginning of the screen load time. It will remain on the screen as long as the target image loads. Once the target image loads with the fade-in animation, the placeholder image will be removed from the screen.
2.The fadeInImage constructor will help create a placeholder on the screen as the target image continues to load with the animation. Once the target image loads completely, this constructor will remove the placeholder through a fade-out action and display only the original picture.
3.You can define several properties within the child widget where you are actually coding for the image based on the action type and animation quality you require. For example, when you define Alignment, the property decides the particular image alignment concerning the border. Similarly, when you define FadeInDuration property, you can set a specific value for the total time taken for the image to appear ultimately with the fade in animation.
How to create a fade-in animation for the images using flutter?
To create the fading animation for the image when it gets displayed on the screen, you have to use the FadeInImage Widget. However, as it is compatible with different image types, like the ones taken from the Internet, stored in the local device, or the built-in memory, you won’t have to worry about using the Widget for incorporating the animation.
Fade in Animation with In-memory Image
You must import that transparent_image package to easily create the transparent placeholder where the image URL will be defined. This package comes in the library functions of fluttered, so you won’t have to code from scratch. You can even determine the position where the image should be displayed on the screen by creating the const Class file within the child widget.
Fade in Animation with Asset Bundle Image
In this process, you can take the image from the asset bundle stored in any location. First, create a project on flutter with an extension of YAML and then add the asset to the file. You must add the asset at the beginning of the code because the interpreter will read that the image type is taken from the acid bundle and work on the animation accordingly.
Once you incorporate the asset into the file, you must define the constructor function with FadeInImage.assetNetwork(). Within this function, you must determine the placeholder and the image URL.
Conclusion
Most flutter developers rely on the built-in properties to create fading animation for the images. This is because the work can be reduced considerably, and the animation incorporated with the image will be more accurate and efficient. Moreover, for the accurate result and achieve recognizable success to your project, you may take a help from the best flutter app development companies in USA to take your project to the next level and maximum goal completion. It is always a great choice to work with industry recognized professionals to achieve your business goals on time.
