calculateMaxLevel method

void calculateMaxLevel(
  1. List<TreeRowNode> treeRowNodes, {
  2. int level = 0,
})

Calculates the maximum depth (level) of the tree structure.

Implementation

void calculateMaxLevel(List<TreeRowNode> treeRowNodes, {int level = 0}) {
  for (var treeRowNode in treeRowNodes) {
    maxLevel = max(maxLevel, level);
    calculateMaxLevel(treeRowNode.rows, level: level + 1);
  }
}
