fnx_gallery

Easy to use AngularDart gallery component.

Live demo

Getting started

First of all, in a Dart app you have to prepare list of images and optionally some caption provider:

List<Image> images = [];

List<String> names = [
  "butterfly.jpg",
  "tunnel.jpg",
  "coast.jpg",
  "flower.jpg",
  "meadow.jpg",
];

ExampleComponent() {
  for (var name in names) {
    name = "imgs/$name";
    Image i = Image(name, thumbSrc: name+"?thumg=1", htmlCaptionProvider: () => name);
    images.add(i);
  }
}

In your template, you can use the component like this:

<fnx-gallery
    [images]="images"
    [withCaptions]="true"
    [withThumbnails]="true"></fnx-gallery>
    ...

Caption provider

htmlCaptionProvider is a function which returns FutureOr<String> and you can use is to fetch your image caption from an asynchronous source (server, etc.).

Caption is handled as HTML, and is displayed using innerHtml with NodeTreeSanitizer.trusted, please make sure your caption can be TRUSTED!

Navigation

Your user can navigate through your gallery by simply pressing the left/right buttons or on mobile also by swiping to left or right.

fnx-gallery element

fnx_gallery package contains <fnx-gallery> element. It's a simple position: fixed; element which you can use as a gallery.

Specify dependency in pubspec.yaml:

dependencies:
  fnx_gallery: ^1.0.0

Run pub get and in your "index.dart" (or whatever is the name of your main script):

import 'package:fnx_gallery/fnx_gallery.dart';

Closing the gallery

We recommended to use *ngIf to show and hide the gallery. <fnx-gallery> emits (close) event, which indicates that the user clicked on the close button (or pressed ESC key etc.). Hide the gallery after this event.

Element inputs

You use some of these AngularDart inputs to modify the element:

input name	data type	purpose
images	List<Image>	List of images of the gallery.
selectedImage	Image	Selected image object, default 0th.
withCaptions	bool	Show captions bellow the images.
withThumbnails	bool	Show thumbnails at the bottom of the gallery.
