instance.
// Before

width: MediaQuery.of(context).size.width,
height: MediaQuery.of(context).size.width,
)
// After
Container(
width: context.width,
height: context.width,

// True if width be larger than 800context.isPhone
// True if the shortestSide is smaller than 600pcontext.isTablet
// True if the current device is Tabletcontext.isSmallTablet
// True if the shortestSide is largest than 600pcontext.isLargeTablet
// True if the shortestSide is largest than 720p
MediaQuery as Inherited Model Old Way X
MediaQuery.of(context).size; MediaQuery.of(context).padding; MediaQuery.of (context). orientation; By calling MediaQuery.of(context).size, the widget will rebuild when any of the MediaQuery properties change (less performant).
New Way ✓
MediaQuery.sizeof(context); MediaQuery.paddingOf(context); MediaQuery.orientation of (context); By calling MediaQuery.sizeof(context), the widget will rebuild only when the size changes, avoiding unnecessary rebuilds.
context.mqSize
// The same of MediaQuery.sizeOf(context)context.mqHeight
// The same of MediaQuery.sizeOf(context).heightcontext.mqWidth
context.mqPadding
// similar to [MediaQuery.paddingOf(context)]context.mqViewPadding
context.mqViewInsets
context.mqOrientation
context.mqAlwaysUse24HourFormat
context.mqDevicePixelRatio
context.mqPlatformBrightness
context.mqTextScaleFactor
//Check in what platform the app is running
MyPlatform.isAndroid
MyPlatform.isIOS
MyPlatform.isMacOS
MyPlatform.isWindows
MyPlatform.isLinux
MyPlatform.isFuchsia
//Check the device type
MyPlatform.isMobile
MyPlatform.isDesktop
//All platforms are supported independently in web!
//You can tell if you are running inside a browser
//on Windows, iOS, OSX, Android, etc.
MyPlatform.isWeb
// Returns a value<T> according to the screen size
// can give value for:
// mobile: if the shortestSide is smaller than 600
// tablet: if the shortestSide is smaller than 1200
// desktop: if width is largest than 1200
context.responsiveValue<T>(
T? mobile,
T? tablet,
T? desktop,
),
// Example
Container(
child: context.responsiveValue(
mobile: Container(
color: Colors.yellow,
width: context.width,
height: context.height,
),
tablet: Container(
color: Colors.green,
width: context.width,

MaterialPageRoute(builder: (context) => SecondScreen()),
);
// After
// for push
context.push(SecondScreen());
context.pushNamed('/home');
// for back , you can also add back result data
context.pop();
// for replace
context.pushReplacement(SecondScreen());
context.pushReplacementNamed('/home');
// popUntil
context.popUntil('/login');

context.push(SecondScreen(), rootNavigator: true);
context.pushReplacement(SecondScreen(), rootNavigator: true);
context.popUntil('/login', rootNavigator: true);
context.routeSettings;

context.routeArguments;
Widget Extensions #
This extension is reduced more code.

20.0.heightBox
// for width
20.0.widthBox
Padding

Flexible #
/// Before
Flexible(

Shimmer Effect
Container(height: 50,width: 50,).applyShimmer();
you can also change color of shimmer using Color baseColor
, Color highlightColor
.
Nil Widget
Sometimes, according to a condition, we want to display nothing. Usually when we can't return null, we would return something like const SizedBox()
for example.
This is good, but it has some performance impacts since SizedBox
creates a RenderObject
. The RenderObject
lives in the render tree and some computations are performed on it, even if it paints nothing on the screen.
We can do better, we can have a widget which does not create a RenderObject
, while being still valid. The Nil
widget is the minimal implementation for this use case. It only creates an Element
and does nothing while it's building. Because the optimal way to use it, is to call const Nil()
, it also comes with a nil
constant that you can use everywhere (which is a const Nil()
).
// Good
text != null ? Text(text) : const Container()
// Better
text != null ? Text(text) : const SizedBox()
// BEST
text != null ? Text(text) : nil
or
if (text != null) Text(text)
SliverToBoxAdapter #
Text(text).sliver;
// is same as
SliverToBoxAdapter(
child: Text(text),
);
Other
Now we can just add round corners, shadows, align, and added gestures to our Widgets.
Container(
height: 100,
width: 100,)
.withRoundCorners(backgroundColor: Colors.grey)
.withShadow()
.alignAtCenter()
.toCenter()
.withTooltip('My Tooltip')
.paddingOnly(left: 10)
.paddingAll(20)
.onTap(() => print('tap'))
.onLongPress(() => print('long press'))
Automatic detect platform and show material and cupertino dialog
context.showAlertDialog(title: 'title',
message: 'message',)
List Extensions #
notNullWidget
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget?>[
Container(
height: 100,
width: 100,
color: Colors.red,
).showIf(true),
Container(
height: 100,
width: 100,
color: Colors.green,
).showIf(false),
].notNullWidget(), // returns only not null widgets
),
SeparatedBy
Row(
mainAxisAlignment: MainAxisAlignment.center,
children: [
const Text('Hello').paddingAll(5),
const Text('World').paddingAll(5),
const Text('Seperated').paddingAll(5),
const Text('By').paddingAll(5),
const Text('Commas').paddingAll(5),
].separatedby(
const Text(','),
),
),
Date Extensions #
// for check two date are same or not
date.isSameDate(otherdate); // its return bool (true/false)
// for check date is today's date
date.isToday // its return bool (true/false)
// for check this date is yesterday's date
date.isYesterday // its return bool (true/false)
Number Extensions #
Future & Duration
Utility to delay some callback (or code execution).
print('+ wait for 2 seconds');
await 2.delay();
print('- 2 seconds completed');
print('+ callback in 1.2sec');
1.delay(() => print('- 1.2sec callback called'));
Easy way to make Durations from numbers.
print(1.seconds + 200.milliseconds);
print(1.hours + 30.minutes);
print(1.5.hours);
5.isLowerThan(4);
5.isGreaterThan(4);
5.isEqual(4);
String Extensions #
//your name => Your Name,
'your name'.capitalize();
//your name => Your name,
'your name'.capitalizeFirst();
//your name => yourname
'your name'.removeAllWhitespace();
// match any RegExp
'dsts'.hasMatch("'r'[A-Z]");
//return bool if match RegExp
'123'.isNumericOnly();
'dsf'.isAlphabetOnly();
'Ajh'.hasCapitalletter();
'true'.isBool();
Async Extensions #
An extention to help dealing with all the possible states of an AsyncSnapshot
in a StreamBuilder
/ FutureBuilder
.
Reduces boilerplate code signifigantly by moving each possible state into it's own function.
StreamBuilder(
stream: incomingMessagesStream,
builder: (context, snapshot) {
snapshot.when(
data: (data, isComplete) {
return Column(
children: [
Text('Latest Message: $data'),
if (isComplete) Text('No More Message'),
]
);
},
error: (error, stackTrace) {
return Text('We have an error');
},
loading: () {
return CircularProgressIndicator();
},
);
},
);
also you can use maybeWhen
, Similar to [when], but allows [data] callback to be optional.
Color Extensions #
Darken
The darken
method darkens the color by a specified percentage. The percentage should be between 0 and 100. By default, the color is darkened by 10%.
Color darkRed = Colors.red.darken(20); // Darkens the red color by 20%
Lighten
The lighten method lightens the color by a specified percentage. The percentage should be between 0 and 100. By default, the color is lightened by 10%.
Color lightRed = Colors.red.lighten(20); // Lightens the red color by 20%
Also Added Some Extra color extensions like: string hax to color, brightness, and change specific RGB color value.
Url Strategy #
With a simple call of setPathUrlStrategy
, your Flutter web app does not have a leading #
in the URL anymore 🚀
void main() {
// Here we set the URL strategy for our web app.
// It is safe to call this function when running on mobile or desktop as well.
setPathUrlStrategy();
runApp(MyApp());
}
