As of my last update in September 2023, Flutter was gaining immense popularity as a versatile and powerful framework for building cross-platform mobile applications. It provided a vast collection of widgets to create visually appealing and interactive user interfaces. While I don't have real-time data on the current trends, I can highlight ten popular widgets that were frequently used and appreciated by Flutter developers at that time.

Container Widget

The Container widget was one of the fundamental building blocks in Flutter. It allowed developers to create a box-like container that could be customized with various properties like color, padding, margin, border, and alignment. It served as a versatile layout element for holding other widgets.

AppBar Widget

The AppBar widget was typically used at the top of the screen to create an app bar that held a title, actions, and an optional leading widget (usually a back button). The app bar facilitated navigation and provided a consistent user experience across screens.

ListView Widget

The ListView widget enabled developers to create a scrollable list of widgets, making it perfect for displaying a dynamic set of items. It supported both vertical and horizontal scrolling, and it could be customized with various children, separators, and scroll controllers.

GridView Widget

The GridView widget allowed developers to arrange items in a grid layout. It supported both fixed and dynamic item counts and provided options for controlling the alignment and spacing between the grid items.

Card Widget

The Card widget helped in creating attractive, material-design style cards. It was widely used to present content in a visually appealing and organized manner. Cards could include text, images, buttons, and other widgets.

TextField Widget

The TextField widget facilitated the input of text from users. It provided a way to collect user data and handle various text-related operations like validation, input formatting, and focus control.

AlertDialog Widget

The AlertDialog widget was used to display a dialog box with a title, content, and action buttons. It was a convenient way to show important messages, confirmations, or prompts to users.

Image Widget

The Image widget was used to display images from various sources, such as the network, local storage, or assets. It supported different image formats and allowed developers to control aspects like caching and loading behavior.

IconButton Widget

The IconButton widget was a button with an icon that performed specific actions when tapped. It was commonly used in app bars, lists, and other interactive elements.

BottomNavigationBar Widget

The BottomNavigationBar widget provided a navigation bar at the bottom of the screen, allowing users to switch between different views or pages within the app with just a tap.

These ten widgets were among the most commonly used and appreciated in the Flutter community due to their versatility, ease of use, and their ability to help developers build visually stunning and interactive mobile applications. However, the Flutter ecosystem is constantly evolving, and newer widgets may have gained popularity since my last update.
