Starting the Flutter widget
Rendering this component with gpt_markdown…
This is the real GptMarkdown Flutter widget, rendered with the exact Markdown input shown here.
Markdown input
1> A useful detail from the model.
2> It can span more than one line.Default behavior
Runtime behavior
Quote markers are stripped, then the inner content is rendered as Markdown again.
Accessibility note
Quoted content retains text semantics and is visually separated without relying on color alone.
Theming & styling
Theme layering guideBlockQuoteStyle is the component's appearance surface. Set only the values you need; style-sheet values merge field-by-field with the active theme and package defaults.
| Style class | Available fields |
|---|---|
| BlockQuoteStyle | barWidth · barColor · barRadius · backgroundColor · padding · margin · textStyle |

Widget Function(BuildContext context, Widget content, BlockQuoteStyle style)
Use this only when the default widget structure is no longer the right shape. The resolved style or configuration is passed where applicable.
Safely override the default
A custom component list replaces a default list entirely. Put your matching component first, then append the package defaults so every other Markdown feature continues to render.
1// Passing components replaces its defaults. Prepend to override matching syntax,
2// then keep every built-in component after it.
