renderer

在这里插入图片描述

graphic中tooltip的TooltipGuide类提供了renderer方法,接收三个参数Size类型,Offset类型,Map<int, Tuple>类型。可查到的文档是真的少,所以只能在源码中扒拉例子,做符合需求的修改。

官方github示例

官方示例

这个例子感觉像是tooltip和提供的那些属性的源码实现,然后改变了背景颜色等,但如果实现想echarts那样对每条线的数据前增加颜色块区分,还是要自己摸索。先看一下这个例子都做了什么吧

List<MarkElement> simpleTooltip(
    Size size,
    Offset anchor,
    Map<int, Tuple> selectedTuples,
  ) {
    // 返回的元素列表
    List<MarkElement> elements;

    // 生成tooltip内容
    String textContent = '';
    // 选中的数据 ({date: xxx, name: 线条1, points: xxx}, {date: xx, name: 线条2, points: xx}...)
    final selectedTupleList = selectedTuples.values;
    // 选中的数据的字段名列表
    // 单条线:[date, points]
    // 多条线:会通过name区分不同线的数值[date, name, points]
    final fields = selectedTupleList.first.keys.toList();

    // 如果只有一条线
    if (selectedTuples.length == 1) {
      // 取出选中的数据
      final original = selectedTupleList.single;
      // 取出第一个字段的值
      var field = fields.first;
      // 将第一个字段的值放入到tooltip的第一行
      /**
       * 此时的数据结构是:
       * date: 2023-11-24
      */
      textContent += '$field: ${original[field]}';
      // 遍历字段名列表
      for (var i = 1; i < fields.length; i++) {
        // 取出第i个字段
        field = fields[i];
        // 将第i个字段的值放入到tooltip的第二行
        /**
         * 遍历后的数据结构是:
         * date: 2023-11-24
         * points: 123
        */
        textContent += '\n$field: ${original[field]}';
      }
    } else {
      // 如果有多条线
      // 遍历选中的数据(几条线几条数据),将每个数据的第二个字段和第三个字段的值放入到tooltip的第二行和第三行
      for (var original in selectedTupleList) {
        // 取出第一个字段
        final domainField = fields.first;
        // 取出最后一个字段
        final measureField = fields.last;
        /**
         * 遍历结束后的数据结构是:
         * 2023-11-24:线条1
         * 2023-11-24:线条2
         * ....
        */
        textContent += '\n${original[domainField]}: ${original[measureField]}';
      }
    }

    // 提出一些变量
    const textStyle = TextStyle(fontSize: 12, color: Colors.white);
    const padding = EdgeInsets.all(5);
    const align = Alignment.topRight;
    const offset = Offset(5, -5);
    const elevation = 1.0;
    const backgroundColor = Colors.black;

    final painter = TextPainter(
      text: TextSpan(text: textContent, style: textStyle),
      textDirection: TextDirection.ltr,
    );
    painter.layout();

    // 计算tooltip的宽高
    final width = padding.left + painter.width + padding.right;
    final height = padding.top + painter.height + padding.bottom;

    // 调整tooltip弹框(包含内容)的位置
    final paintPoint = getBlockPaintPoint(
      anchor + offset,
      width,
      height,
      align,
    );

    // 调整tooltip弹框(不包含内容)的位置
    final window = Rect.fromLTWH(
      paintPoint.dx,
      paintPoint.dy,
      width,
      height,
    );

    // 计算tooltip文本的位置
    var textPaintPoint = paintPoint + padding.topLeft;
    
    elements = <MarkElement>[
      RectElement(
          rect: window,
          style: PaintStyle(fillColor: backgroundColor, elevation: elevation)),
      LabelElement(
          text: textContent,
          anchor: textPaintPoint,
          style:
              LabelStyle(textStyle: textStyle, align: Alignment.bottomRight)),
