5 Top Flutter Widgets For Developers
August 7 , 2020 Posted by Admin
If you have ever delved into Flutter, you might have thought that it has a very steep learning curve. It might be true. A lot of people say the same thing. But the learning curve is steep because we probably take on too much at the same time. We try to learn everything at once and fail at it. The key is to learn one thing at a time so that we can manage the curve according to our learning styles and according to our intellect. Once you do that, you will realize that learning Flutter is not that big a deal and you were just making a mountain out of a molehill.
What are Flutter Widgets?
Here we are going to discuss Flutter Widgets, what they are, and what they do. If you want to do custom app development, you will need to work with widgets. In fact, if you want to do any kind of app development you will have to use widgets.
Widgets are elements that you use in your user interface. Anything could be a widget. It could be the text, a button, checkboxes, images, and so much more. Suffice it to say that everything that you use in your user interface is a widget whether you are going for custom Android development or iOS.
If you know what custom iOS development is or what Android development is, then you will fully understand the concept of views (in Android) and UIViews (in iOS). Just think of your widgets as blueprints. They tell Flutter where you want to place certain elements and how to render them for the outcome.
Here, we have a list of the top 5 Flutter widgets for developers, young and experienced alike.
1. Safe Area Widget
Do you know the concept of notches? If you are building apps for the modern-day devices, you must. You might not like them, but you are stuck with them. The main purpose of notches is to shift the elements from the front face of our phones. But the problem is that rounded corners and notches screw up the layout of the app. When you use Flutter to build your custom apps, you have the choice of using the Safe Area Widget to work around this problem.
This widget does nothing more than to wrap your main layout so that there is no overlapping of content or clipping. It’s easy to use and you can ensure that your users see all the content that you want them to see.
2. Expanded Widget
In Flutter, you have to work on a screen layout that is comprised of rows and columns. Whatever you do, you have to do it between these rows and columns. Having a grid like this is beneficial as you can arrange all your widgets on the screen in an organized and systematic manner. The problem that arises here is that the rows and columns can decide to distribute your elements according to the available space. What does this mean? It means that all your elements might come on the screen on the left side or they can have an equal amount of space between them. When this happens, there might be some extra space left between the elements.
What are you going to do with the extra space? How will you fill it?
You will just use the Expanded Widget to take care of it. Just put the element inside this widget to make it expandable. Whatever extra space is left, the expanded widget will take it up.
3. Wrap Widget
Earlier we discussed that we place elements on the screen on a grid of rows and columns. These two are widgets themselves and they make designing the layout smooth and effortless. You can place your widgets on these rows and elements any way that you like. But what happens when you have a widget that is too wide to fit into the rows? When this happens, you see a black and yellow block on your screen and the accompanying error ‘Right overflowed by 471 pixels’ or something like that. So, how are you going to take care of this problem?
With the Wrap Widget, of course.
The Wrap Widget is the same as the rows and columns grid that you’ve been working on. The only difference, or should we say advantage, is that it has the power to adjust the elements that you want to put on the screen. It knows how much space is available on the screen and adjusts the elements accordingly. You can arrange the elements horizontally or vertically. You can even change the direction property.
4. Rich Text Widget
If you want to display a paragraph in Flutter with different styles then the Rich Text Widget is the one that you want to use. What you do is implement multiple TextSpan widgets inside the Rich Text Widget and set a different style for each of them. This way, you will create a tree of TextSpan objects, each of them inside the main Rich Text Widget. You can show multiple styles on the same line or in the same paragraph.
5. ClipRect and ClipRRect
These two are almost the same that’s why we thought of discussing them together. You can use them to clip an element with a rectangular shape. The only difference is that while ClipRect uses a rectangular shape with edges, the ClipRRect widget uses a rectangular shape with rounded corners. Other than that, they both have the same purpose.
So, these are some of the most used and popular widgets in Flutter. They are also the basic building blocks in any app development project. So, make sure you explore them fully and find out all your options. Happy Coding!
