Neumorphic design has taken the Flutter community by storm, and for good reason. Its futuristic, 3D-esque aesthetic is both visually stunning and highly customizable. However, as many developers have discovered, this design trend comes with its own set of challenges. One of the most frustrating issues is when the Neumorphic design disappears when resizing the window in Flutter. In this article, we’ll delve into the root causes of this problem and provide a step-by-step guide on how to overcome it.
Understanding Neumorphic Design in Flutter
Before we dive into the solution, it’s essential to understand the basics of Neumorphic design in Flutter. Neumorphism is a design trend that uses soft, rounded shapes and subtle shadows to create a 3D-like effect. In Flutter, this is achieved using a combination of `Container`, `BoxDecoration`, and `BoxShadow` widgets.
Container(
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(20),
boxShadow: [
BoxShadow(
blurRadius: 10,
spreadRadius: 5,
color: Colors.grey.withOpacity(0.5),
),
],
),
child: // your child widget here
)
The Problem: Neumorphic Design Disappears on Resize
Now, let’s get to the crux of the issue. When you implement Neumorphic design in Flutter, it often disappears or becomes distorted when you resize the window. This is because the design relies heavily on absolute values for padding, margin, and shadow radius. When the window resizes, these values become relative, causing the design to break.
Why Does Neumorphic Design Disappear on Resize?
There are several reasons why Neumorphic design disappears on resize in Flutter:
- Absolute values**: As mentioned earlier, Neumorphic design relies on absolute values for padding, margin, and shadow radius. When the window resizes, these values become relative, causing the design to break.
- Widget size changes**: When the window resizes, the size of the widgets changes, affecting the positioning and layout of the design elements.
- Layout constraints**: Neumorphic design often uses `Container` widgets with fixed sizes, which can lead to layout constraints issues when the window resizes.
Solving the Resize Conundrum
Now that we’ve identified the root causes of the issue, let’s explore the solutions:
1. Use Relative Values Instead of Absolute Values
One of the most effective ways to overcome the resize issue is to use relative values instead of absolute values. This can be achieved using `MediaQuery` to get the screen size and adjust the design elements accordingly.
import 'package:flutter/material.dart';
class NeumorphicContainer extends StatelessWidget {
@override
Widget build(BuildContext context) {
final screenWidth = MediaQuery.of(context).size.width;
final screenHeight = MediaQuery.of(context).size.height;
return Container(
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(screenWidth * 0.1),
boxShadow: [
BoxShadow(
blurRadius: screenWidth * 0.01,
spreadRadius: screenWidth * 0.005,
color: Colors.grey.withOpacity(0.5),
),
],
),
child: // your child widget here
);
}
}
2. Use LayoutBuilder to Adjust Widget Sizes
Another approach is to use `LayoutBuilder` to adjust the widget sizes based on the available screen space.
import 'package:flutter/material.dart';
class NeumorphicContainer extends StatelessWidget {
@override
Widget build(BuildContext context) {
return LayoutBuilder(
builder: (context, constraints) {
return Container(
width: constraints.maxWidth * 0.8,
height: constraints.maxHeight * 0.4,
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(20),
boxShadow: [
BoxShadow(
blurRadius: 10,
spreadRadius: 5,
color: Colors.grey.withOpacity(0.5),
),
],
),
child: // your child widget here
);
},
);
}
}
3. Use Flexible Widgets to Adapt to Screen Size
Using flexible widgets such as `Flexible` or `Expanded` can help adapt the design to different screen sizes.
import 'package:flutter/material.dart';
class NeumorphicContainer extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Row(
children: [
Flexible(
flex: 2,
child: Container(
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(20),
boxShadow: [
BoxShadow(
blurRadius: 10,
spreadRadius: 5,
color: Colors.grey.withOpacity(0.5),
),
],
),
child: // your child widget here
),
),
Flexible(
flex: 1,
child: // another widget here
),
],
);
}
}
4. Use a Custom Resize Widget
For more complex layouts, you can create a custom resize widget that adjusts the design elements based on the screen size.
import 'package:flutter/material.dart';
class ResizeWidget extends StatelessWidget {
@override
Widget build(BuildContext context) {
return LayoutBuilder(
builder: (context, constraints) {
final screenWidth = constraints.maxWidth;
final screenHeight = constraints.maxHeight;
return Stack(
children: [
// background widget
Positioned(
top: screenHeight * 0.1,
left: screenWidth * 0.1,
child: Container(
width: screenWidth * 0.8,
height: screenHeight * 0.4,
decoration: BoxDecoration(
color: Colors.grey,
borderRadius: BorderRadius.circular(screenWidth * 0.1),
boxShadow: [
BoxShadow(
blurRadius: screenWidth * 0.01,
spreadRadius: screenWidth * 0.005,
color: Colors.grey.withOpacity(0.5),
),
],
),
),
),
// foreground widget
Positioned(
top: screenHeight * 0.2,
left: screenWidth * 0.2,
child: Container(
width: screenWidth * 0.6,
height: screenHeight * 0.3,
decoration: BoxDecoration(
color: Colors.white,
borderRadius: BorderRadius.circular(screenWidth * 0.1),
),
),
),
],
);
},
);
}
}
Conclusion
In conclusion, Neumorphic design disappearing on resize in Flutter is a common issue that can be overcome by using relative values, `LayoutBuilder`, flexible widgets, and custom resize widgets. By understanding the root causes of the problem and applying these solutions, you can create stunning Neumorphic designs that adapt seamlessly to different screen sizes.
Remember, when working with Neumorphic design in Flutter, it’s essential to consider the layout constraints and widget sizes. By doing so, you can create designs that are not only visually appealing but also flexible and responsive.

Frequently Asked Questions
Stuck with Neumorphic design issues in Flutter? We’ve got you covered! Here are the top 5 questions and answers to help you troubleshoot and resolve the pesky problem of Neumorphic design disappearing when resizing the window.
Why does my Neumorphic design disappear when I resize the window in Flutter?
The Neumorphic design might disappear due to the lack of a specified width or height for the widgets. When the window resizes, the widgets adapt to the new size, causing the design to break. To fix this, ensure that you define explicit width and height values for the widgets or use LayoutBuilder to dynamically adjust the sizes based on the available space.
How can I maintain the aspect ratio of my Neumorphic design when resizing the window?
To maintain the aspect ratio, use the FittedBox widget with the BoxFit.contain property. This ensures that the child widget scales proportionally to fit the available space while preserving its original aspect ratio. You can also use the AspectRatio widget to define a fixed aspect ratio for your design.
What’s the role of the Material widget in Neumorphic design, and how does it affect resizing?
The Material widget is a fundamental component in Neumorphic design, providing the elevated and depressed effects. When you resize the window, the Material widget’s elevation and depression effects might break if not properly configured. To avoid this, ensure that you set the Material widget’s elevation property to a non-zero value and define a suitable depth for the depression effect.
How can I debug Neumorphic design issues when resizing the window in Flutter?
To debug Neumorphic design issues, use the Flutter Inspector tool to visualize the widget tree and identify the problematic widgets. You can also use the debugPrint function to log the widget sizes and positions during resizing. Additionally, use the Flutter Debugger to step through your code and examine the widget properties during runtime.
Are there any Flutter packages that can help me with Neumorphic design and resizing issues?
Yes, there are several Flutter packages available to help you with Neumorphic design and resizing issues. The neumorphic package provides an easy-to-use implementation of Neumorphic design principles. Additionally, packages like flutter_responsive_grid and responsive_framework can help you create responsive layouts that adapt to different screen sizes and orientations.
