onPatternStart abstract method

void onPatternStart(
  1. int patternId,
  2. double x,
  3. double y,
  4. double width,
  5. double height,
  6. Float64List transform,
)

A pattern has been decoded.

All subsequent pattern commands will refer to this pattern, until onPatternFinished is invoked.

Implementation

void onPatternStart(int patternId, double x, double y, double width,
    double height, Float64List transform);
