getTitle property
getTitle is used to draw titles outside the RadarChart
getTitle is type of GetTitleByIndexFunction so you should return a valid RadarChartTitle
for each index
(we provide a default angle
= index * 360 / titleCount)
getTitle: (index, angle) {
switch (index) {
case 0:
return RadarChartTitle(text: 'Mobile or Tablet', angle: angle);
case 2:
return RadarChartTitle(text: 'Desktop', angle: angle);
case 1:
return RadarChartTitle(text: 'TV', angle: angle);
default:
return const RadarChartTitle(text: '');
}
}
Implementation
final GetTitleByIndexFunction? getTitle;
