An overview of the most commonly used Flutter widgets and how to use them effectively

Flutter is a popular open-source framework for building mobile applications. It provides a vast array of widgets that can be used to create beautiful and functional user interfaces. In this blog post, we’ll take a look at the most commonly used Flutter widgets and how to use them effectively.

1. Container Widget

The Container widget is one of the most versatile widgets in Flutter. It allows you to create a box-like element that can be customized with various properties such as padding, margin, background color, border, and more.

Here’s an example of a Container widget that has a blue background color and a 10-pixel margin:

Container(
  margin: EdgeInsets.all(10),
  color: Colors.blue,
);

2. Text Widget

The Text widget is used to display text in your application. It supports various properties such as font size, color, alignment, and more.

Here’s an example of a Text widget that displays the text “Hello World!” with a font size of 24 and a red color:

Text(
  'Hello World!',
  style: TextStyle(
    fontSize: 24,
    color: Colors.red,
  ),
);

3. Row and Column Widgets

The Row and Column widgets are used to display children widgets horizontally and vertically, respectively. They allow you to create complex layouts by combining multiple widgets.

Here’s an example of a Column widget that contains two Text widgets and a Container widget:

Column(
  children: [
    Text('Title'),
    Text('Subtitle'),
    Container(
      margin: EdgeInsets.all(10),
      color: Colors.blue,
    ),
  ],
);

4. Image Widget

The Image widget is used to display images in your application. It supports various properties such as width, height, fit, and more.

Here’s an example of an Image widget that displays an image from a URL with a width of 200 pixels and a height of 200 pixels:

Image.network(
  'https://example.com/image.jpg',
  width: 200,
  height: 200,
);

5. ElevatedButton and TextButton Widgets

The ElevatedButton and TextButton widgets are used to create buttons in your application. They support various properties such as text, color, onPressed, and more.

Here’s an example of an ElevatedButton widget that displays the text “Click Me!” and changes the background color to blue when pressed:

ElevatedButton(
  onPressed: () {},
  child: Text('Click Me!'),
  style: ElevatedButton.styleFrom(
    primary: Colors.blue,
  ),
);

6. TextField Widget

The TextField widget is used to create input fields in your application. It supports various properties such as controller, keyboardType, decoration, and more.

Here’s an example of a TextField widget that accepts text input and displays a hint text:

TextField(
  decoration: InputDecoration(
    hintText: 'Enter text here',
  ),
);
