gallerize

Flutter package for creating Flutter Gallery-like gallery/demo for your package/widget.

Purpose of this package

The gallerize package can be used to demonstrate what YOUR package/widget is for. It is inspired by Flutter Gallery (see repo on GitHub), therefore the name "gallerize".

gallerize allows you to take your own package/widget and create an app around it which provides a description, a preview and exemplary source code, just like Flutter Gallery does it for the material and cupertino widgets. gallerize saves you from creating boilerplate code for creating a gallery app structure, importing themes etc.

Example

Suppose you created an awesome widget (lib/my_fancy_widget.dart) which you want to show to your friends/workmates:

class MyFancyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Container(
      color: Colors.blue,
      child: Center(
        child: Text("My Fancy Widget!"),
      ),
    );
  }
}

Using gallerize you can easily create an app that looks as follows:

How to use it?

1. Add dependency to pubspec.yaml:

dependencies:
  gallerize: <current_version>

2. Add all the relevant source files to the assets of pubspec.yaml:

  assets:
    - lib/my_fancy_widget.dart

3. Import the gallerize package:

import 'package:gallerize/gallerize.dart';

4. Use the GallerizePage widget within your app:

MaterialApp(
  title: 'My Fancy Widget Gallery',
  theme: GallerizeThemeData.darkThemeData,
  home: GallerizePage(
      name: "My Fancy Widget",
      description:
          "This is a gallery app demoing the fancy widget that I created. "
          "With the help of the fancy widget, you can create the "
          "fanciest app you have ever seen!",
      codeFile: "lib/my_fancy_widget.dart",
      preview: MyFancyWidget()),
)

GallerizePage expects at least a name and a description, which are shown in the info-tab. codeFile is used to tell gallerize which dart code to show in the code-tab. preview defines the widget that should be shown in the preview-tab.

Setting the app theme

To change the theme for your gallery-app, you can use two themes offered by gallerize, which were taken from Flutter Gallery:

MaterialApp(
  theme: GallerizeThemeData.darkThemeData,
)

The two offered themes are GallerizeThemeData.darkThemeData and GallerizeThemeData.lightThemeData.

Changing the syntax highlighting theme

gallerize internally uses flutter_highlight for syntax highlighting. See all available themes.

To use a certain syntax highlighting theme, do the following:

1. Import the desired theme (e.g. a11y-dark.dart):

import 'package:flutter_highlight/themes/a11y-dark.dart';

2. Set the theme in your GallerizePage:

GallerizePage(
    highlightingTheme: a11yDarkTheme
    ...
)

The default theme used is draculaTheme ('package:flutter_highlight/themes/dracula.dart')

TODO

• Github Pages + Github Action Setup - to host the example project, with CD - any push to master branch triggers flutter build web -> commit/createPR to gh-pages branch-> changes reflected to "Github Pages"
• Add "Gallery" Shield - which users can put in their README (https://shields.io/)
• Multi-screen size support (toggle for fullscreen/mobile view)
