Usage

PendartView Widget

PendartView is a simple widget for displaying Pendart markup as formatted text:

import 'package:pendart/preview.dart';

// ...

PendartView(
  text: "This is **bold** and this is %%italic%%",
  isDarkMode: false, // Set to true for dark mode
)

PendartEditor Widget

PendartEditor provides a full editor experience with a formatting toolbar:

import 'package:pendart/editor.dart';

// ...

PendartEditor(
  initialText: "# Start typing here",
  height: 400,
  isDarkMode: false, // Set to true for dark mode
  onTextChanged: (text) {
    // Do something with the updated text
    print('Text updated: $text');
  },
)

Markup Syntax

Pendart uses a simple markup language:

Markup	Result
**text**	Bold text
%%text%%	Italic text
__text__	Underlined text
~~text~~	Strikethrough text
! Text	# Heading 1
!! Text	## Heading 2
[]	☐ Unchecked checkbox
[x]	☑ Checked checkbox
@@url text@@	text
[[image.jpg]]	Image
---	Horizontal rule
code	Inline code
::: and :::	Code block

Theme Support

As of version 0.3.0, Pendart has improved theme support that integrates with your app's theme:

Using System Theme

Both PendartView and PendartEditor can automatically use your app's theme:

import 'package:pendart/preview.dart';
import 'package:pendart/editor.dart';

// The widgets will automatically use your app's ThemeData
PendartView(
  text: "This text respects your app's theme",
)

PendartEditor(
  initialText: "# Start typing here",
  height: 400,
)

Custom Theme

You can also provide a custom theme:

// For light theme
final lightTheme = ThemeData(
  brightness: Brightness.light,
  primarySwatch: Colors.blue,
  // other properties...
);

// For dark theme
final darkTheme = ThemeData(
  brightness: Brightness.dark,
  primaryColor: Colors.blueAccent,
  // other properties...
);

// Pass the theme directly to the widgets
PendartEditor(
  initialText: "# Custom themed editor",
  theme: isDarkMode ? darkTheme : lightTheme,
)

Deprecated Properties

The isDarkMode property is deprecated in favor of using ThemeData:

// Old way (still supported but deprecated)
PendartEditor(
  initialText: "Text",
  isDarkMode: true, // Deprecated
)

// New way
PendartEditor(
  initialText: "Text",
  // No need to set isDarkMode, it will use your app's theme
)
