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.

🗂 Widgets

Preview	Widget	Description
	Neumorphic	The main Neumorphic Widget, a container which adds white/dark gradient depending on a lightsource and a depth
	NeumorphicButton	A neumorphic button that plays with the depth to respond to user interraction
	NeumorphicRadio	A set of neumorphic button whith only one selected at time, depending on a value and groupValue
	NeumorphicCheckbox	A button associated with a value, can be checked/unckecked, if checked, takes the accent color
	NeumorphicSwitch	An On/Off toggle, associated with a value, if toggled, takes the accent color
	NeumorphicSlider	A Neumorphic seekbar (range slider), the user can select a value in a range
	NeumorphicProgress	A determinate progress, takes the displayed percentage
	NeumorphicIndeterminateProgress	An inderminate progress-bar
	NeumorphicIndicator	A vertical / horizontal indicator bar, takes a percentage
	NeumorphicBackground	Take the background color of the theme, can clip the screen with a borderRadius

📦 Neumorphic

Neumorphic(
  boxShape: NeumorphicBoxShape.roundRect(borderRadius: BorderRadius.circular(12)), 
  style: NeumorphicStyle(
    shape: NeumorphicShape.concave,
    depth: 8,
    lightSource: LightSource.topLeft,
    color: Colors.grey
  ),
  child: ...
)

☝️ 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
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	The box shape of a Neumorphic element. Stadium : roundrect with cirlces on each side

🔧 Shapes

Shape	Widget	Image	Condition
Flat			depth >= 0 && shape == Flat
Convex			depth >= 0 && shape == Convex
Concave			depth >= 0 && shape == Concave
Emboss			depth < 0

🎨 Neumorphic Theme

NeumorphicTheme(
    usedTheme: UsedTheme.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: ...
)

To retrieve the current used theme :

final theme = NeumorphicTheme.currentTheme(context);
final baseColor = theme.baseColor;
final accentColor = theme.accentColor;
...

Toggle from light to dark

NeumorphicTheme.of(context).currentTheme = CurrentTheme.DARK;

Know if using dark

if(NeumorphicTheme.of(context).isUsingDarkMode){
  
}
