Widget Slide #
await pres.addWidgetSlide((size) => Center(

decoration: BoxDecoration(
border: Border.all(color: Colors.blueAccent, width: 5.0),
color: Colors.redAccent,
),
child: const Text("This is a widget")),
));
copied to clipboard
This is asynchronous because the widget needs to be rendered to an image thanks to the screenshot package.
Markdown #
It is also possible to create a presentation using markdown.
await pres.addSlidesFromMarkdown('MARKDOWN SOURCE');
copied to clipboard
The markdown follows the same format for md2googleslides.
Slide Background #
Solid Color #
Colors need to be in HEX format and not include the leading #.
slide.background.color = 'FF0000';
copied to clipboard
To convert from a Flutter color to HEX, use the toHex method.
slide.background.color = Colors.red.toHex();
copied to clipboard
Image #
slide.background.image = ImageReference(
path: './samples/images/sample_jpg.jpg',
name: 'Sample Jpg',
);
copied to clipboard
Speaker Notes #
slide.speakerNotes = 'Notes'.toTextValue();
copied to clipboard
Show Slide Numbers #
slide.showSlideNumber = true;
copied to clipboard
Or for an entire presentation.
pres.showSlideNumbers = true;
copied to clipboard
Images #
Images use the ImageReference class. The path can be the base64 encoded string, remote url, asset image or local file path.
The name is used for the alt and can be overridden with a description.
When the presentation is saved all images will be downloaded and saved in the presentation.

Running on Flutter Web will cause a CORS error when using remote urls if the server does not have the correct headers. To get around this, you can use a proxy server.
