  • Option to let users define their custom link handling 🛠️

• Flexible Content Source: Fetch content from various sources like:

  • Local assets using fromLocal()

  • Network URLs using fromNetwork()

  • Custom async functions using custom()

🚀 Getting started

1. Add mayr_md_cms to your pubspec.yaml:

   dependencies:
       mayr_md_cms: # check for the latest version on pub.dev
   

2. Instal the package:

   flutter pub get
   

3. Import it into your Dart file:

   import 'package:mayr_md_cms/mayr_md_cms.dart';
   

   Alternatively, you could install it using the command

   flutter pub add mayr_md_cms
   

🚀 Usage

Here’s how to use MayrMdCms and display Markdown content in your Flutter app:

1. Import the Package

Import the package into your Dart file:

import 'package:mayr_md_cms/mayr_md_cms.dart';

2. Fetch and Display Content

From Local Asset:

If you have a Markdown file in your assets:

MayrMdCms.fromLocal(
  'assets/content.md',
  config: mayrMdCmsConfig // Config is optional
);

// More on the config later

From Network URL:

If you want to fetch the Markdown content from a URL:

MayrMdCms.fromNetwork(
  'https://example.com/content.md',
  config: mayrMdCmsConfig // Config is optional
  dioClient: dioClient, // Optional
);

// You could choose to pass your own instance of dio that would be used in getting the page.
// This is useful if for example authentication is required to access the page or extra dio configurations are needed

Using a Custom Future:

You can also pass a custom Future to fetch content, giving you full control over the data source:

MayrMdCms.custom(() async {
  // Custom async fetch logic
  return 'Your custom markdown content goes here';
});

3. Internal Actions on Links

To create internal navigation in your app, define internal links in your Markdown (e.g., [About Us](internal:about_us)), and map them to your custom widgets:

Internal actions and handlers can be used as below:

1. Define your internal actions on the config:

   MayrMdCms.fromNetwork(
     'https://example.com/content.md',
     config: MayrMdCmsConfig(
       internalActions: {
         "internal:action_one": (context) => print("Link One clicked"),
         "internal:action_two": (context) => print("Link two clicked"),
       },
     ),
   );
   

2. Add the links to your markdown

   You could choose to perform [Action One](internal:action_one) or even [Action Two](internal:action_two)
   

Now when user clicks on any of the action links, the associated actions would be run

4. Extend the Package

For more control, you can create a custom class that extends MayrMdCms and override methods or add new logic:

class CustomMdCms extends MayrMdCms {
  @override
  MayrMdCmsConfig get config => MayrMdCmsConfig(
    loadingWidget: MyCustomLoadingWidget(),
    errorWidget: MyCustomErrorWidget(),
    emptyWidget: MyCustomEmptyWidget(),
    shrinkWrap: true,
    scrollPhysics: const NeverScrollableScrollPhysics(),
    internalActions: {
      "internal:indicate_interest": (context) {...},
      "internal:go_to_signup": (context) => context.go("/signup"),
      "internal:switch_theme_dark": (context) => MyThemeSwitcher.toDark(),
    },
    markdownStyleSheet: MyCustomMarkdownStyleSheet()
  );
}

After the package has been extended, it can then be used as below:

CustomMdCms().local(...);
CustomMdCms().network(...);
CustomMdCms().custom(...);

🛠️ Configuration

Certain aspects of the package can be configured using the MayrMdCmsConfig(...) class. A sample configuration is:

MayrMdCmsConfig(
  loadingWidget: MyCustomLoadingWidget(),
  errorWidget: MyCustomErrorWidget(),
  emptyWidget: MyCustomEmptyWidget(),
  shrinkWrap: true,
  scrollPhysics: const NeverScrollableScrollPhysics(),
  internalActions: {
    "internal:indicate_interest": (context) {...},
    "internal:go_to_signup": (context) => context.go("/signup"),
    "internal:switch_theme_dark": (context) => MyThemeSwitcher.toDark(),
  },
  markdownStyleSheet: MyCustomMarkdownStyleSheet()
)
