This project contains all the bootstrap sass source files. This project will be useful to create new themes using sass.

bootstrap_sass is a Sass-powered version of Bootstrap, ready to drop right into your Sass powered applications.


1. Create a new project with next structure:

  ├─ pubspec.yaml
  ├─ web
  │  ├─ index.html
  │  ├─ _variables.scss
  │  ├─ theme.scss
  │  └─ ... other files and folders ...
  └─ lib
     └─ ... lib files and folders ...

2. In the pubspec.yaml file add the bootstrap_sass and sass_builder dependencies.

  bootstrap_sass: ^4.1.2 # change for the latest version
  sass_builder: ^2.0.0 # change for the latest version

3. Then in _variables.scss add the variables you want to modify

//== Colors
//## Gray and brand colors for use across Bootstrap.

$gray-base: #800625;
$gray-darker:            lighten($gray-base, 13.5%); // #222
$gray-dark:              lighten($gray-base, 20%);   // #333
$gray:                   lighten($gray-base, 33.5%); // #555
$gray-light:             lighten($gray-base, 60%);   // #999
$gray-lighter:           lighten($gray-base, 93.5%); // #eee

$brand-primary:          #e72b42;
$brand-success:          #73A839;
$brand-info:             #033C73;
$brand-warning:          #DD5600;
$brand-danger:           #22afc7;

4. In the theme.scss add the styles you need to change.

@import 'variables' // variables should be before bootstrap to override variable values
@import 'packages/bootstrap_sass/stylesheets/bootstrap';

// Cerulean 3.3.5
// Bootswatch
// -----------------------------------------------------

@mixin btn-shadow($color){
  @include gradient-vertical-three-colors(lighten($color, 8%), $color, 60%, darken($color, 4%));
  filter: none;
  border-bottom: 1px solid darken($color, 10%);

// Navbar =====================================================================

.navbar {
  @include btn-shadow($navbar-default-bg);
  filter: none;
  @include box-shadow(0 1px 10px rgba(0, 0, 0, 0.1));

  &-default {

    .badge {
      background-color: #fff;
      color: $navbar-default-bg;

  &-inverse {
    @include gradient-vertical-three-colors(lighten($navbar-inverse-bg, 8%), lighten($navbar-inverse-bg, 4%), 60%, darken($navbar-inverse-bg, 2%));
    filter: none;
    border-bottom: 1px solid darken($navbar-inverse-bg, 10%);

    .badge {
      background-color: #fff;
      color: $navbar-inverse-bg;

  .navbar-nav > li > a,
  &-brand {
    text-shadow: 0 1px 0 rgba(0, 0, 0, 0.1);

5. Generate the required css by running:

build_runner build

or if you prefer you could watch for changes and run:

build_runner watch

6. Finally in the index.html you will add the link to theme.css as bellow:

<!DOCTYPE html>
<html lang="en">
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <!-- you could add bootstrap.css file if you don't create your own theme -->
  <!--<link rel="stylesheet" href="packages/bootstrap_sass/sass/bootstrap.css">-->
  <!-- you can also add theme.css -->
  <link rel="stylesheet" href="theme.css">
  <!-- ... content here ... -->
