Create Responsive Layouts for Mobile, Web and Desktop with Flutter

IMPORTANT! This package is in a beta preview and built with Dart null-safety.

Following the Material Design Guidelines, Layout encourage consistency across platforms, environments, and screen sizes by using uniform elements and spacing.

Getting started

This package aims to provide the tools to implement a responsive layout in an easy and consistent way.

If you want to learn more in detail about layout in Material Design I recommend you the official website.

Let's get started!

Everything starts with the Layout widget. Usually added at the top of your widget tree, but you can place it wherever you need it. It uses its widget constraints to calculate its breakpoint, columns, gutters, and margins.

  @override  Widget build(BuildContext context) {    return Layout(      child: MaterialApp(      ....      ),    );  }

Breakpoints

A breakpoint is the range of predetermined screen sizes that have specific layout requirements. At a given breakpoint range, the layout adjusts to suit the screen size and orientation.

Each breakpoint range determines the number of columns, and recommended margins and gutters, for each display size.

By default the breakpoints are defined as:

  • xs: 0 – 599
  • sm: 600 – 1023
  • md: 1024 – 1439
  • lg: 1440 – 1919
  • xl: 1920 +
  @override  Widget build(BuildContext context) {    if(context.breakpoint > LayoutBreakpoint.md)      return TabletView();    else      return MobileView();  }

LayoutValues

A layout value is relative to the width of the screen. This way you can define responsive variable, reuse them and apply them when needed.

final double padding = context.layout.value(xs: 0.0, sm: 12.0, md: 24.0, lg: 32.0, xl: 48.0);

The most important layout values are the ones relative to the breakpoint. This are the most common an useful as you can define a value for a different breakpoint sizes. If a breakpoint is not provided, its value will correspond to the first previous/smaller breakpoint.

final double padding = context.layout.value(     xs: 0.0,  // sm value will be like xs 0.0     md: 24.0, // lg value will be like md 24.0     xl: 48.0);

Layout values can be reused in different parts of the app with even different Layout widgets. For that they need to be created as

final displaySidebar = LayoutValue.breakpoint(xs: false, md: true);final horizontalMargin = LayoutValue((layout) {    double margin = layout.width >= 500 ? 24.0 : 16.0;    margin += 8.0 * layout.visualDensity.horizontal;    return EdgeInsets.symmetric(horizontal: margin);});

Then it can be used in any widget that as some Layout up in the tree as:

return Column(  children: [    Padding(      padding: horizontalMargin.resolve(context),      child:child,    ),    if(displaySidebar.resolve(context))      SideBar(),    ),  ],);

You can also create values relative to the layout width like.

final displaySidebar = LayoutValue((layout) => layout.width > 600);

Margins

Margins are the space between content and the left and right edges of the screen.

  @override  Widget build(BuildContext context) {    return Margin(      child: Text('This text'),    );  }

Margin widths are defined as fixed values at each breakpoint range. To better adapt to the screen, the margin width can change at different breakpoints. Wider margins are more appropriate for larger screens, as they create more whitespace around the perimeter of content.

By default the margin values are the ones from the Material Design Guidelines. 16dp for screens with a width less than 720dp and 24 for bigger screens. You can override this values in any moment by providing the margin param.

Fluid Margins

Some times you want to have a fixed width that stays the same across screen sizes.

  @override  Widget build(BuildContext context) {    return FluidMargin(      child: Text('This text'),    );  }

Fluid margins are dinamically updated to keep a fixed size of its inner child. This fixed sizes are by default the ones from the Material Design Guidelines but can also easily customizable.

AdaptiveBuilder

A widget tha allows easily to build responsive layouts

  @override  Widget build(BuildContext context) {    return AdaptiveBuilder(      xs: (context) => LayoutWithBottomNavigationBar(),      lg: (context) => LayoutWithTrailingNavigationBar(),    );  }

or for more complex cases

  @override  Widget build(BuildContext context) {    return  AdaptiveBuilder.builder(      builder: (context, layout, child) {        if (layout.breakpoint < LayoutBreakpoint.lg) {          return LayoutWithBottomNavigationBar(child: child);        } else {          return LayoutWithTrailingNavigationBar(child: child);        }      },      child: child,    );  }

Contributing

If you want to take the time to make this project better, you can open an new issue, of a pull request.

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add layout

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:  layout: ^1.0.2

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:layout/layout.dart'; 

example/lib/main.dart

import 'package:example/layout_bar.dart';import 'package:flutter/material.dart';import 'package:flutter/rendering.dart';import 'package:layout/layout.dart';import 'example.dart';void main() {  runApp(MyApp());}class MyApp extends StatelessWidget {  // This widget is the root of your application.  @override  Widget build(BuildContext context) {    return Layout(      child: MaterialApp(          title: 'Flutter Demo',          debugShowCheckedModeBanner: false,          theme: ThemeData(            appBarTheme: AppBarTheme(              color: Colors.white,            ),            scaffoldBackgroundColor: Colors.grey[200],            primarySwatch: Colors.blue,          ),          builder: (context, child) {            return Column(              crossAxisAlignment: CrossAxisAlignment.stretch,              children: [Expanded(child: child!), LayoutBar()],            );          },          home: MyHomePage(title: 'Layout')),    );  }}

CSS Layout Grid

One of the most challenging aspects of building webpages is managing layout. HTML and CSS offer several different methods to control layout. The layout options include using normal flow, floats, multi-column layout, flexbox, and CSS Grid. To allow for more complex layouts, CSS Grid aims to be a major step forward by giving developers more control over layout and arrangement of elements on a web page.

Great Learning Resources

There are several really good and helpful resources available to learn CSS Grid. Here’s a quick rundown of resources that helped me learning CSS Grid.

Visual Examples of Layouts

Fun and Games — to learn CSS Grid

Setting up the Grid

CSS Grid works by creating a grid container using the display: grid property. The immediate children of the grid container are called grid items.

An essential feature of using CSS Grid is setting up the columns and rows to be used in the grid. This is done with the grid-template-columns and grid-template-rows properties. There are many different ways to set up a grid.

Let’s say we want a grid with five columns. There’s a few ways to set this up. To build columns, we’ll use the grid-template-columns property. To create five columns it’s necessary to add five values, on for each column.

.container {
  display: grid;
  grid-template-columns: 20rem 100px auto 30% 25em;
}

As shown in the code sample, it’s possible to add sizes using different units of measurement, including pxemrem%, and auto. CSS Grid also introduces a new unit, fr, which means fractional unit. This is used by assigning size to the grid based on values entered and dividing up the remaining space based on a division of fractional units.

.container {
  display: grid;
  grid-template-columns: 15rem 1fr 2fr;
}

In the example above, 15rem is assigned and the remaining space is divided between the two columns, the 2nd column getting 1fr out of 3 units and the last column getting 2fr out of 3 units.

The same concepts for columns work for rows. Adding the grid-template-rows property allows for the explicit creation of grid rows.

.container {
  display: grid;
  grid-template-columns: 15rem 1fr 2fr;
  grid-template-rows: 20rem 400px;
}

This addition establishes two explicit rows in the grid. The row sizes are defined by units. This code creates a grid that is 3 columns by 2 rows and creates 6 total grid cells. Now it’s time for content to flow into the grid.

<div class="container">
  <h1>Title</h1>
  <p>Lorem ipsum dolor sit amet consectetur adipisicing elit. Dolor, totam.</p>
  <img src="sun.jpg" alt="Sun" />
  <h4>Image subtitle</h4>
  <p>Velit dolor unde explicabo illum ipsa temporibus, hic sed error.</p>
  <div>Additional content</div>
</div>

The HTML above includes a <div class="container"> that is used as a grid container. The 6 elements that are the immediate children of the div are the grid items. Since there are only 6 items, each one will fit into the 6 grid cells defined in the CSS code above. If another grid item is added, however, this will now be a total of 7 children element. In this case, CSS Grid will automatically create a new row to include this element. The new row constitutes what is known as the implicit grid - automatically added to the grid, although not explicitly defined.

There are certain situations where a developer does not know exactly how many rows may be needed for a grid — in the case of repeating or auto-generated content, for example. In these situations, it’s possible to make use of the grid-auto-columns and the grid-auto-rows properties. These properties set a pre-determined size for implicitly created columns and rows.

CSS Layout — Flexbox

Creating layouts with normal flow, positioning, and floats is possible, but not very user-friendly for developers. That’s where flexbox comes in to help. With flexbox it’s possible to build much more complex layouts than by just using normal flow, positioning, and floats. Flexbox allows developers to manage tricky layouts such as vertical and horizontal alignment and gain precise control over spacing and sizing of layout elements.

CSS Layout — Flexbox

The Flex Model

Flexbox is built upon use of several key concepts.

  • Flex Container — has display: flex applied and is the parent element that encompasses all elements displayed with a flexbox layout.
  • Main Axis — runs in the direction that flex items are laid out and has a main start and main end for the start and end of the axis.
  • Cross Axis — runs perpendicular to the main axis and has a cross start and cross end for the start and end of the axis.
  • Flex Items — elements laid out inside the flex container are called flex items.

Implementation

To designate a flex container, the element uses the css entry display: flex.

The parent or flex container also specifies if the flex container will make use of a row or column layout. This is done using the flex-direction property.

Wrapping Flex Items

Flex items will display as a row or column and use up as much space as needed to fit all the items into the row. This works okay when there are few items, but causes problems when items begin to overflow their containers or stretch the page display beyond the browser maximum width. To handle this type of situation, there is a property called flex-wrap that will wrap content within a flex container that is to large for the height or width of the container.

Flexbox — Everything You Need to Know (Part: 1 — Flex-Container)

F

lexbox had appeared as a blessing for all frontend web developers. Before its arrival, designing a complex layout required too many works. Flexbox made our walking toward complex web UIs easier as well as faster. And in this era of modern web design, we can not think of an interactive UI without flexbox. In this article, we’ll discuss flexbox in-detail and play with various flex properties. So, guys, are you ready? Let’s kick it off.

Okay, before starting, can you tell me why we’re calling it FLexbox? Yes, you are right. The answer is “Because of being flexible”. Layout designed by the flexbox can easily resize and organize its elements to make the layout responsive.

Flex Components

To use Flexbox we need at least two components. They are —

  1. **Flex Parent or Flex Container: — **Mainly it contains a bunch of elements and applies flex properties upon them.
  2. **Flex Child or Flex Item: — **Elements that are arranged inside the flex-container.

This image is made with ❤️ by myself

Flex Axes

Flexbox has two axes —

  1. **Main Axis: — **Elements inside of the flex container are arranged along with this axis. By default, this axis is set in the horizontal direction.
  2. Cross Axis: — By default, this axis is set in the Vertical direction, perpendicular to the main axis.

But this arrangement of flex axes is not fixed all the time. It can be changed using the flex-direction property.

This image is made with ❤️ by myself

Flex Properties

In flexbox, we have 2 types of elements. One is Flex Container and the other is Flex Item. For both of them, there are different flex properties. All of them are listed below —

Flex Container: —

  • Display
  • Width & Height
  • Flex Direction
  • Flex Wrap
  • Justify Content
  • Align Content
  • Align Items

Flex Item: —

  • Height & Width
  • Order
  • Flex Basis
  • Flex Grow
  • Flex Shrink
  • Align Self
  • Margin

In this part, we are going to discuss flex-container. But We will discuss them all in several parts. So nothing to worry. Hopefully, it’ll be a nice journey in the flex world to all.

UiKit Responsive Starter Template

This is image title

Starter templates are ready-made layouts for making a website. Just you have to customize it with your own information. So here we made responsive starter template layouts in UiKit.

In these templates, we used the UiKit framework with customizing the CSS class. Here we used navbar, slider, off-canvas, card, and also used form components to contact us. Also, we made a beautiful footer using gird and list-type components. This fully responsive for mobile and tablet-side.

Make it yours now by using it, downloading it and please share it.

Accessible Fonts: Please, STOP Using PX For Screen!

In my work as an accessibility consultant, one of the classic problems that’s always been an issue with websites is how so many artists under the delusion that they are “web designers” continue to spew out pixel based layouts.

Pixels are from an accessibility standpoint the least useful measurement. Because so many displays of different sizes have the same resolutions, or displays of the same sizes have different resolutions, there is no “physical standard” by which a pixel is based. As such you’re stuck either relying on zoom (which mangles raster images) or not being able to target your layouts based on the user’s needs.

To explain why PX are bad, and what you should use instead, I think it would help to cover the major measurement types you can/would use in web design.
