shapeAt method

dynamic shapeAt(int offset)

Returns the shape at the specified byte distance from the beginning of the file. Mind that:

• it's your responsibility to ensure the offset corresponds to the actual beginning of a shape struct
• once you call this, reading with hasNext/next on sparse shapefiles will be broken (we don't know anymore at which shape we are)

Implementation

dynamic shapeAt(int offset) async {
  disableShxUsage();
  if (randomAccessEnabled) {
    await goTo(offset);
    var rec = await nextRecord();
    return rec?.shape();
  }
  throw StateError("Random Access not enabled");
}
