Are you a Flutter developer who’s ever felt puzzled by which button to use in your app’s UI? You’re not alone. Many developers struggle to pick the right button type, often resorting to unnecessary customizations. But fear not! This guide is here to demystify Flutter buttons, helping you make informed choices for your app’s design needs.
TextButton:
The TextButton is your basic, no-frills button. It’s perfect for simple actions like navigating pages or confirming choices. Avoid adding unnecessary customizations to it. Let it blend seamlessly into your UI, or customize it with a style or theme if needed.
Basic TextButton with onPressed function enabled
TextButton(
// onPressed function that gets triggered when button is pressed

// Add your onPressed code here!
},
child: const Text(
'This is a TextButton Demo - Enabled',
), // Text displayed on the button
),Disabled TextButton with onPressed function set to null
TextButton(
// Button is disabled
// as onPressed function is null
onPressed: null,
child: Text(
'This is a TextButton Demo - Disabled',
),
),TextButton with icon and onPressed function enabled
TextButton.icon(
// onPressed function that gets
//triggered when button is pressed
onPressed: () {
// Add your onPressed code here!
},
icon: const Icon(
Icons.access_alarm,
), // Icon displayed before the text

return ShaderMask(
shaderCallback: (Rect bounds) {
return LinearGradient(
begin: Alignment.topLeft,
end: Alignment.bottomRight,
colors: [
Colors.red,
Colors.green,
],
).createShader(bounds);
},
blendMode: BlendMode.srcATop,

),TextButton with custom foreground using DecoratedBox and onPressed function enabled
TextButton(
style: TextButton.styleFrom(
foregroundBuilder: (context, states, child) {
return DecoratedBox(
decoration: BoxDecoration(
border: states.contains(MaterialState.hovered)
? Border(
bottom: BorderSide(

),
)
: const Border(), // Border displayed when button is hovered

).copyWith(
side: MaterialStateProperty.resolveWith<BorderSide?>((states) {
if (states.contains(MaterialState.hovered)) {
return BorderSide(
width: 3,
color: Colors.yellow.withOpacity(
1.0,
), // Border color when button is hovered
);
}
return null; // Border color when button is not hovered
}),
),
child: const Text(
'TextButton #7',
style: TextStyle(
color: Colors.white,
),
), // Text displayed on the button
),FilledButton:
Consider FilledButton as a TextButton with a bit more flair. It’s great for important actions that demand attention, like saving or confirming. While it offers tonal variations, remember, it’s essentially a styled TextButton.
A filled button with a solid background color
FilledButton(
onPressed: () {
// Define the action that should be taken when the button is pressed.
// Currently, this is an empty function.
},
child: const Text(
"This is a filled button - Mihir Pipermitwala",
),
),A tonal filled button with background color
FilledButton.tonal(
onPressed: () {
// Define the action that should be taken when the button is pressed.
// Currently, this is an empty function.
},
child: const Text(
"This is a filled button (tonal)",
),
)ElevatedButton:
ElevatedButton adds depth to your UI with its elevation and native Android-like appearance. Use it when you want your button to stand out or convey hierarchy. But avoid using it in popups or dialogues where default animations might clash.
A Disabled ElevatedButton with custom text style
ElevatedButton(
onPressed: null,
child: const Text(
'Disabled',
),
),
ElevatedButton(
onPressed: () {
// Add your onPressed code here!
},
child: const Text(
'Enabled',
),
),OutlinedButton:
If you need a button with a subtle outline, OutlinedButton is your friend. It’s ideal for medium-emphasis actions. Its clean design ensures it doesn’t overpower your UI elements.
OutlinedButton with a custom onPressed callback
OutlinedButton(
onPressed: () {
debugPrint(
'Received click',
);
},
child: const Text(
'Click Me',
),
),IconButton:
Need a button with just an icon? IconButton is the way to go. It offers click animations and various button styles, making it versatile for different UI needs.
Basic IconButton with an icon and onPressed function
IconButton(
icon: const Icon(Icons.filter_drama),
onPressed: () {
// Add your onPressed code here!
},

onPressed: () {
// Add your onPressed code here!

onPressed: () {
// Add your onPressed code here!

A disabled Cupertino button with a standard transparent background

onPressed: null,
child: Text('Disabled'),
