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
