Bootstrap web components in Dart. For more information on the different components, check out Bootstrap's documentation.
You can view all the implemented components (and the Dart code) in the deployed page (https://juancastillo0.github.io/bootstrap_dart/). The code for the deployed page is in the web/bootstrap_examples.dart file.
We currently support the following versions:
- Bootstrap 5.1.3 https://getbootstrap.com/docs/5.1/
- Bootstrap Icons 1.9.1 https://icons.getbootstrap.com/
- Bootstrap Dark 1.1.3 https://vinorodrigues.github.io/bootstrap-dark-5/
Add the dependencies to your pubspec.yaml
Since the package is agnostic to the rendering package, can chose any of the supported frameworks: deact_bootstrap, jaspr_bootstrap or rad_bootstrap.

</html>We provide the Bootstrap scss along with the Bootstrap Dark dark mode scss. With them, and using package:sass_builder to compile scss files, you can customize Bootstrap and only import the components you need.
Add sass_builder to your dependencies
dev_dependencies:
sass_builder: ^2.1.2Create an scss file (web/bootstrap.scss) that customizes variables and imports the Bootstrap scss
// Include any default variable overrides here (though functions won't be available)
$primary: #01388a; // was #0d6efd;
// Import the bootstrap nightshade scss.
// This includes the default Bootstrap and dark scss
// https://github.com/vinorodrigues/bootstrap-dark-5/blob/main/docs/bootstrap-nightshade.md
@import "package:bootstrap_dart/scss/bootstrap-nightshade";
// You can import the `bootstrap-icons.scss` in here also
@import "package:bootstrap_dart/icons/bootstrap-icons";
// Then add additional custom code here
:root {
// shade-color function is from bootstrap.
// Use in css with `background-color:var(--light-darker);`
--light-darker: #{shade-color($light, 5%)};
--dark-darker: #{shade-color($dark, 10%)};
}Edit your html file to import the compiled css and the darkmode.js file:

</html>Because we imported the bootstrap-icons.scss in the web/bootstrap.scss file, the previous html already supports Bootstrap icons. However, you may also import the css directly:
<link rel="stylesheet" href="./packages/bootstrap_dart/icons/bootstrap-icons.css">Since the web/bootstrap.scss is importing bootstrap-nightshade, you can use the html.dark css class selector to change the styles of different elements when the dark mode is selected (CSS class dark over the html element):
html.dark .code-section {
background-color: var(--bs-dark-alt);
}To toggle dark mode you may use the API in package:bootstrap_dart/dark_mode/dark_mode.dart. Which uses the underling darkmode.js file.
import 'package:bootstrap_dart/dark_mode/dark_mode.dart' show DarkMode;
final darkMode = DarkMode();
DeactNode darkModeSwitch() {
return check(
label: txt('Dark Mode'),
id: 'darkModeSwitch',
type: CheckType.switch_,
checked: darkMode.inDarkMode,
inline: true,
onChange: (_) {
darkMode.toggleDarkMode();
},
);
}You may use the DarkMode.inDarkModeChanges Stream to subscribe to changes or the inDarkModeValue constructor parameter to use a package:mobx observable in the DarkMode.inDarkMode getter.
You can view all the implemented components (and the Dart code) in the deployed page (https://juancastillo0.github.io/bootstrap_dart/). The code for the deployed page is in the web/bootstrap_examples.dart file.

A service for compiling, executing and tracking the build process and deployment. With a git repository, one can set up a CLI pipeline for continuous integration and delivery. All the commands are tracked in realtime. This is a simple personal project for deploying in a VM. The service uses web sockets and the source code repository has three projects:
- A Leto Shelf GraphQL server. Everything is saved in memory
- A Dart client using
package:graphqlandpackage:graphql_codegen - A Web Dart client using
package:jasprand jaspr_bootstrap.
You can view the code in the Github repo. The client UI and some links to the different GraphQL Schema UI explorer is deployed in this page.
This repository contains multiple Dart packages. The main bootstrap package and the bindings for external rendering frameworks.
Main package with all Bootstrap components. Independent of the rendering framework.
The main package does not have a rendering framework, for that you need to provide a Bootstrap Renderer. We implement the rendering bindings for multiple frameworks in the following packages:
deact_bootstrap for package:deact
SPA framework inspired by React.
jaspr_bootstrap for package:jaspr
Support for SPA, SSR, Islands with good test coverage. Inspired by Flutter.
You need to use the MobXHooksObserverComponent at the root of the Component tree.
This component is exported in jaspr_bootstrap.
rad_bootstrap for package:rad
SPA framework with Hooks, great test coverage and performance. Inspired by Flutter and React.
To support multiple rendering frameworks a global bootstrapRenderer should be overridden. The code is found in lib/bootstrap/bootstrap_renderer.dart.
At the moment, the framework should support the following interface.
- Hooks (useRef, useState and useEffect)
- Render HTML elements
- Render text nodes
- Render a node with multiple children (React's fragment)
- Create functional components with Hooks support
/// A renderer used within the Bootstrap components to create html elements.
///
/// A "node" is in reference to a Node, Widget or Component in each of the frameworks.
class BootstrapRenderer<N> {
/// Returns a node that renders an html element of the given [tag].
/// The [attributes], [listeners] and [children] should be set for the html element.
/// The [ref] should be populated when an effect using [BootstrapBuildContext.hookEffect] is run.
N el(
String tag, {
Map<String, String>? attributes,
Iterable<dynamic>? children,
Object? key,
Map<String, void Function(html.Event)>? listeners,
Ref<html.Element?>? ref,
}) =>
throw _error;
/// Returns a node that renders an html text node.
N txt(String text) => throw _error;
/// Returns a node that renders multiple [children] nodes.
N fragment(List<dynamic> children) => throw _error;
/// Returns a node that support hooks with the API in [BootstrapBuildContext].
N fc(dynamic Function(BootstrapBuildContext) builder, {Object? key}) =>
throw _error;
}
abstract class BootstrapBuildContext {
/// A reference to a mutable value of type [T] associated with this context.
/// [create] will be called only once for setting up the initial value.
Ref<T> hookRef<T>(T Function() create);
/// The [effect] should be called when the html elements are rendered.
/// If any of the [keys] change, [effect] should be re-executed.
/// If [effect] returns a function, it should be called to release resources
/// from the executed [effect] when the keys change or the component is unmounted.
void hookEffect(
void Function()? Function() effect, [
List<Object?>? keys,
bool Function(Object?, Object?)? equals,
]);
/// A reference to a mutable value of type [T] associated with this context.
/// If changed, this should rerender the component associated with this context.
/// [create] will be called only once for setting up the initial value.
State<T> hookState<T>(T Function() create);
}
/// The renderer used within the Bootstrap components to create html elements.
///
/// You should set the `bootstrapRenderer` for Bootstrap Dart to render the components.
/// You can use one of the provided packages:
/// - jaspr_bootstrap
/// - rad_bootstrap
/// - deact_bootstrap
BootstrapRenderer bootstrapRenderer = BootstrapRenderer();
/// A reference to a mutable [value] of type [T].
abstract class Ref<T> {
Ref(this.value);
T value;
}
/// A reference to a mutable [value] of type [T].
/// If changed, this should rerender the component in which this was created.
typedef State<T> = Ref<T>;We provide bindings as a BootstrapRenderer class implementation for the supported frameworks. An usage example for the package:rad framework would be the following:
import 'package:rad/rad.dart';
import 'package:bootstrap_dart/bootstrap/bootstrap_core.dart';
import 'package:rad_bootstrap/rad_bootstrap.dart';
void main() {
/// Set the global `bootstrapRenderer`
RadBootstrapRenderer.setUp();
