~~NOTRANS~~ ~~Title: Group configuration~~ The group panel has different style options. The default (modern) style shows a round rectangle with the group label. The flat style shows a solid line with a label. To use the flat style, simply use: Style.addStyleNames(group, "f_panel_flat"); The modern vs. flat style: {{:flutterui:group_modern.png?nolink&400|}} {{:flutterui:group_flat.png?nolink&400|}} It's also possible to hide the border of modern styled group, with: Style.addStyleNames(group, "f_panel_noborder"); {{:flutterui:noborder.png?nolinkk&400}}
