MarkdownBodyRaw({String data, MarkdownStyleRaw markdownStyle, SyntaxHighlighter syntaxHighlighter, MarkdownLinkCallback onTapLink })

Creates a new Markdown Widget that renders the markdown formatted string passed in as data. You need to pass in a markdownStyle that defines how the code is rendered. Code blocks are by default not using syntax highlighting, but it's possible to pass in a custom syntaxHighlighter.

Typically, you may want to wrap the MarkdownBodyRaw widget in a Padding and a ScrollableViewport, or use the Markdown class

new ScrollableViewport(
  child: new Padding(
    padding: new EdgeInsets.all(16.0),
    child: new MarkdownBodyRaw(
      data: markdownSource,
      markdownStyle: myStyle
    )
  )
)
