Problem Statement
Explain the purpose and usage of Text, Image, and Icon widgets in Flutter.
Explanation
Text widget displays strings with styling options through the style parameter accepting TextStyle objects. You can customize font size, weight, color, letter spacing, line height, and more. Text supports overflow handling with properties like overflow: TextOverflow.ellipsis, maxLines for limiting lines, and textAlign for alignment. Use Text.rich for multiple styles in one text widget with TextSpan.
Image widget displays images from various sources: Image.asset for bundled images in your app, Image.network for remote URLs, Image.file for device files, and Image.memory for byte data. Configure fit property to control how images scale (cover, contain, fill, fitWidth, fitHeight). Use width and height to size images, and cacheWidth/cacheHeight to optimize memory by resizing during decode.
Icon widget displays Material Design icons from Icons class, which contains hundreds of pre-defined icons. Icons are vector graphics that scale perfectly at any size. Customize with size and color properties. Use IconButton to make icons tappable. Icons are lightweight and work well with themes - Icon.color defaults to theme's icon theme color if not specified.
All three widgets are commonly used together in Flutter apps: Text for labels and content, Image for photos and graphics, Icon for symbolic representations. Understanding these fundamental widgets is essential for building any Flutter UI.
