☝️ Playing with LightSource & Depth
🛠️ Attributes #



Attributes
Values
Description




LightSource
TopLeft, BottomRight, etc. / (dx, dy)
The source of light specifit to the theme or the widget, used to project white/dark shadows on neumorphic elements


Shape
Concave / Convex / Flat
The shape of the curve used in the neumorphic container


Depth
-20 <= double <= 20
The distance of the widget to his parent. Can be negative => emboss. It influences on the shadow's color and its size/blur


Intensity
0 <= double <= 1
The intensity of the Light, it influences on the shadow's color


SurfaceIntensity
0 <= double <= 1
The intensity of the Surface, it influences on the concave/convex darkness


Color
any Color
The default color of Neumorphic elements


Accent
any Color
The default accent color of the Neumorphic element when activated (eg: checkbox)


Variant
any Color
The default secondary color of the Neumorphic element (eg: used as second color on the progress gradient)


BoxShape
Circle, RoundRect(radius), Stadium, Path
The box shape of a Neumorphic element. Stadium : roundrect with cirlces on each side


Border
NeumorphicBorder
A border (color/width) to enhance contrast with background and others elements







🔧 Shapes #

Flat


depth >= 0 && shape == Flat

Neumorphic Text #

Text only handle positive depth
child: NeumorphicText(
"I love flutter",
style: NeumorphicStyle(
depth: 4, //customize depth here
color: Colors.white, //customize color here
),
textStyle: NeumorphicTextStyle(
fontSize: 18, //customize size here
// AND others usual text style properties (fontFamily, fontWeight, ...)
),
),

Neumorphic Icon #

child: NeumorphicIcon(
Icons.add_circle,
size: 80,
),
copied to clipboard
How to display SVG icons ?
Simply use https://fluttericon.com/ to export your svg as .ttf & use NeumorphicIcon(YOUR_ICON)

🎨 Custom Shape #

Flutter Neumorphic supports custom shapes, just provide a path to
class MyShapePathProvider extends NeumorphicPathProvider {
@override
bool shouldReclip(NeumorphicPathProvider oldClipper) {
return true;
}

@override
Path getPath(Size size) {
return Path()
..moveTo(0, 0)
..lineTo(size.width/2, 0)
..lineTo(size.width, size.height/2)
..lineTo(size.width/2, size.height/2)
..lineTo(size.width, size.height)
..lineTo(0, size.height)
..close();
}
}
copied to clipboard
And use NeumorphicBoxShape.path
Neumorphic(
style: NeumorphicStyle(
boxShape: NeumorphicBoxShape.path(MyShapePathProvider()),
),
...
),
copied to clipboard
You can import the Flutter logo as a custom shape using
Neumorphic(
style: NeumorphicStyle(
shape: NeumorphicBoxShape.path(NeumorphicFlutterLogoPathProvider()),
),
...
),
copied to clipboard
🔲 Accessibility / Border #
For design purposes, or simply to enhance accessibility,
you can add a border on Neumorphic widgets

Neumorphic(
style: NeumorphicStyle(
border: NeumorphicBorder(
color: Color(0x33000000),
width: 0.8,
)
),
...
)
copied to clipboard
You can enable/disable it (eg: listening an Accessibility Provider) with isEnabled
border: NeumorphicBorder(
isEnabled: true,
color: Color(0x33000000),
width: 0.8,
)
copied to clipboard
Note that borderColor and borderWidth default values has been added to NeumorphicThemeData
🎨 Neumorphic Theme #


NeumorphicTheme(
themeMode: ThemeMode.light, //or dark / system
darkTheme: NeumorphicThemeData(
baseColor: Color(0xff333333),
accentColor: Colors.green,
lightSource: LightSource.topLeft,
depth: 4,
intensity: 0.3,
),
theme: NeumorphicThemeData(
baseColor: Color(0xffDDDDDD),
accentColor: Colors.cyan,
lightSource: LightSource.topLeft,
depth: 6,
intensity: 0.5,
),
child: ...
)
copied to clipboard
To retrieve the current used theme :
final theme = NeumorphicTheme.currentTheme(context);
final baseColor = theme.baseColor;
final accentColor = theme.accentColor;
...
copied to clipboard
Toggle from light to dark
NeumorphicTheme.of(context).themeMode = ThemeMode.dark;
copied to clipboard
Know if using dark
if(NeumorphicTheme.of(context).isUsingDark){

}

NeumorphicApp #
You can use direcly in your project a NeumorphicApp, surrounding your code
It handle directly NeumorphicTheme & Navigation (and all possibilities of MaterialApp )
void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
// This widget is the root of your application.
@override
Widget build(BuildContext context) {
return NeumorphicApp(
debugShowCheckedModeBanner: false,
title: 'Neumorphic App',
themeMode: ThemeMode.light,
theme: NeumorphicThemeData(
baseColor: Color(0xFFFFFFFF),
lightSource: LightSource.topLeft,
depth: 10,
),
darkTheme: NeumorphicThemeData(
baseColor: Color(0xFF3E3E3E),
lightSource: LightSource.topLeft,
depth: 6,
),
home: MyHomePage(),
);
}
}

What's neumorphic #

Material Cards #
A Modern / Material (upgraded) card usually is a surface floating on top of our perceived background and casting a shadow onto it. The shadow both gives it depth and also in many cases defines the shape itself — as it’s quite often borderless.
Neumorphic cards #
Neumorphic card however pretends to extrude from the background. It’s a raised shape made from the exact same material as the background. When we look at it from the side we see that it doesn’t “float”.

Here's a Nereumorphic Button tap (slowed x2) from the sample app, you can see how the element seems to change its depth to its surface.
