In Flutter, creating a TextField with a hint text but without an underline can be a bit tricky. This guide will walk you through the process of achieving this effect using simple code snippets. Whether you are developing a mobile app or a web interface, the solution can be tailored to fit your needs.
Basic Implementation
To create a TextField without an underline, you can use the InputDecoration widget. Here is a straightforward approach:
TextField(
decoration: InputDecoration.collapsed(
hintText: 'Username'
),
),
This method works well if you only need a hint text without any additional decorations like icons.
Advanced Customization
If you require more control over the TextField appearance, such as adding icons or adjusting padding, you can use the following approach:
TextField(
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'Username',
contentPadding: EdgeInsets.only(left: 15, bottom: 11, top: 11, right: 15),
),
),
This code snippet provides a borderless text field with customizable padding, enabling a more refined user interface design.
Incorporating Border Radius
To add a border radius without using a container, you can modify the InputDecoration like so:
TextField(
decoration: InputDecoration(
border: OutlineInputBorder(
borderSide: BorderSide.none,
borderRadius: BorderRadius.circular(20),
),
hintText: 'Search your trips',
),
),
This approach is ideal when you want a rounded appearance for your text field.
Conclusion
By leveraging the InputDecoration properties in Flutter, you can effectively create a TextField with a hint text and no underline. This solution offers flexibility in styling and functionality, ensuring that your application’s user interface remains clean and intuitive.
