flutter - flutter/dart 中的甘特图

Question

我需要实现类似于此的甘特图 https://www.primefaces.org/showcase/ui/data/timeline/custom.xhtml ，但在charts_flutter或任何其他类似的库中似乎没有这样的图表。 我一直在任何流行的图表库中寻找类似的东西，但没有运气:(

class GanttChart extends StatelessWidget {
  final AnimationController animationController;
  final DateTime fromDate;
  final DateTime toDate;
  final List<Project> data;
  final List<User> usersInChart;

  int viewRange;
  int viewRangeToFitScreen = 6;
  Animation<double> width;

  GanttChart({
    this.animationController,
    this.fromDate,
    this.toDate,
    this.data,
    this.usersInChart,
  }) {
    viewRange = calculateNumberOfMonthsBetween(fromDate, toDate);
  }
