How to set Label and Hint on TextField with Style in Flutter
Introduction
Flutter is a popular framework for building mobile applications, and one of the essential components of any app is the TextField. The TextField widget in Flutter allows users to input text, but it can also be styled and customized to fit the needs of the app. In this article, we will explore how to set labels and hints on TextFields with style in Flutter.
Setting Labels on TextField
Labels on TextFields provide a description of what the field is for, making it easier for users to understand what they need to enter. To set a label on a TextField in Flutter, you can use the `decoration` property and specify the `labelText` property. Here is an example:
“`dart
TextField(
decoration: InputDecoration(
labelText: ‘Username’,
),
)
“`
This will display the label “Username” above the TextField.
Setting Hints on TextField
Hints on TextFields provide a subtle suggestion of what the user should enter. To set a hint on a TextField in Flutter, you can use the `decoration` property and specify the `hintText` property. Here is an example:
“`dart
TextField(
decoration: InputDecoration(
hintText: ‘Enter your username’,
),
)
“`
This will display the hint “Enter your username” inside the TextField when it is empty.
Styling Labels and Hints
To style the labels and hints, you can use the `labelStyle` and `hintStyle` properties respectively. Here is an example:
“`dart
TextField(
decoration: InputDecoration(
labelText: ‘Username’,
labelStyle: TextStyle(
fontSize: 18,
color: Colors.blue,
),
hintText: ‘Enter your username’,
hintStyle: TextStyle(
fontSize: 16,
color: Colors.grey,
),
),
)
“`
This will display the label “Username” in blue with a font size of 18, and the hint “Enter your username” in grey with a font size of 16.
