Top 12 Flutter Widgets to Know in 2021

flutter is one of the most popular frameworks for developing mobile, web, and desktop
applications. It is full of widgets and it makes it more sustainable. Flutter widgets are used for
developing high-quality cross-platform applications because they are customizable and offer
extensive flexibility & fluidity that can be the best fit for any mobile app type. Widget elements
are organized in the form of a widget tree. The manner in which the widgets are placed defines
the operation of the front-end of the native applications screen. The two primary things of Flutter
widgets are the configuration and the widget state. There are lots of Flutter widgets available
and here we’ll discuss the top 11 widgets for developing flutter apps. Before digging into the
flutter widget list, let us see the types of flutter widgets.

Types Of Flutter Widgets

There are two types of Widgets in Flutter- Stateless widget and Stateful widget. Based on the two
types, these widgets are further categorized into 14 different categories as- Async, Accessibility,
Assets, Images and Icons, Layout, Interaction Models, Material components, Animation and
motion, Painting and effects, styling, text.

Top 12 Flutter Widgets.

1. SafeArea
  This widget is best when it comes to developing dynamic and adaptive UI. It helps to adjust the
  screen with various devices of different resolutions. Also, it helps in overcoming the area
  constraints induced by the status bar, notches, navigation bar, etc. Its implementation doesn’t
  allow the design to overlay any of the areas where there is frontend UI visibility constraint and
  so makes it error-free. Hence SafeArea widget is also known as a padding widget that adds
  padding to android or iOS apps wherever there is a constraint. SafeArea widget will also indent
  the child with the necessary padding necessity, particularly for the devices with the Notch like
  iPhone X.

1. ConstrainedBox
  It is a built-in widget available in Flutter SDK. Generally, it is used to add size limitations to the
  child widgets. It allows developers to add flexibility with respect to height and width in a child
  widget. But the widget has limitations when the child is bigger in size than the container. It cuts
  the child’s view, making the front end look somewhat out of the line. This issue can be tackled
  by not defining the maxHeight property and adjusting it to by default value of double. infinity.

1. Align Widget
  You should organize components inside the UI. Flutter can compose these widgets together.
  But how do we position a child under a parent widget? We can use the Align widget. For
  instance, how we choose the position of the text inside a container. The following code shows you
  the result.

1. Layout Builder
  This widget is used to determine the size of the widget and how it depends on the parent
  widgets (height and width properties). Its builder function contains parameters to build the
  context and the incoming box constraints. Within methods, we check the constraints and get a
  decision.

1. FittedBox
  It is a responsive Flutter widget that helps to induce responsiveness into the single child
  assigned to it. You have to add a Row widget as a child in this FittedBox widget. Row widget
  has two containers as its children. In this case, the second child will overflow to one side but,
  this issue is solved with the FittedBox widget. FittedBox widget is used to scale and position the
  child widget inside the parent widget. UI developed with this widget is clean, and dynamic. One
  can use the FittedBox class and enter a child widget while using the FittedBox widget.

1. StreamBuilder
  It is used to synchronize the streams of received data. This widget is supported by Dart
  language that extends support to asynchronous streams of data. StreamBuilder widget takes in
  two arguments- A Stream and A Builder. The widget acts as a pipe that receives an entered data
  from one end and releases it at the other end. Also, registered listeners can be in multiple
  numbers.

1. FloatingActionbutton
  Every flutter developer uses FloatingActionButton for app development. Basically, it is a
  hovering button used to draw attention to a particular element of app content.
  FloatingActionButton is the main widget of the Scaffold widget.

1. Tooltip
  In the app, to express details visually we use icons. But in some cases, users realize the
  meaning of the icon. At that time, we display text labels when tapping or long-press on the icon.
  This is a use of the Tooltip widget.

1. Hero
  Whenever you need to click on an item and route to the next page which relevant to the clicked
  item, you can use the Herp widget with good animation between the transition. With this, you
  can provide a great UI experience to your users.

1. Wrap
  Wrap Widget of Flutter is used to wrap children in a horizontal and vertical placement. Whenever
  you have multiple widgets and you want to use them in a row or column; you can use the Wrap
  widget to prevent content from getting clipped. You can name a direction, as horizontal or
  vertical according to the frontend you need for your application. Also, it helps to define the
  spacing between two widgets.

1. . Opacity
  It is used to make a child inside the container transparent. Also, it changes the child into an
  intermediate buffer and makes it transparent temporarily. The remaining space rearranges
  itself, or you can keep it empty; you can do it both ways.

Flutter Arc Text
Another interesting Flutter widget on the list is Arc Text. Arc Text widget helps in simplifying the
task of writing a code for a text and content available over an arc shape. You can set various
angles and define the content you want to have around the circle, which is next to impossible
to code with Flutter. If you hire Flutter developers from anywhere in the world, they will
implement the same widget if you demand to have a frontend UI over an arc.
