AppButton class final

Botão do Flocks — a ação com rótulo e/ou ícone, variando pelo eixo global AppStyle: filled (primária preenchida), outlined (secundária contornada) e elevated (preenchida com sombra simétrica, sem borda).

Fundo/realce por estado herdam o modelo de cor do DS (contraste AA garantido em hover/press/disabled). Sobre FlocksInteraction (foco-Tab/anel, Enter/Space), com press-scale via AppMotion e loading. Substitui os antigos AppFillButton (→ AppStyle.filled) e AppLineButton (→ AppStyle.outlined).

AppButton(label: 'Salvar', onPressed: save)                            // filled
AppButton(style: AppStyle.outlined, label: 'Cancelar', onPressed: cancel)
AppButton(style: AppStyle.elevated, label: 'Publicar', onPressed: publish)
