Getting Started

You need to first import 'package:photogrammetry/photogrammetry.dart';

  bool isProcessing = false;
  String? complete;
  Photogrammetry? pg;
  String? path;

  @override
  void initState(){
    super.initState();
  }
  @override
  void dispose(){
    pg?.dispose();
    super.dispose();
  }

  Future<void> selectFolder() async {
    try {
      await FilePicker.platform.getDirectoryPath().then((value){
        if(value != null){
          setState((){
            isProcessing = true;
          });
          pg = Photogrammetry()..process(
            pgData: PhotogrammetryData(
              path: value,
              name: 'TestHuman1',
              quality: PhotogrammetryQuality.preview
            ),
            onProgressChanged: (progress){
              setState(() {
                complete = '${(progress*100).toStringAsFixed(2)}%';
              });
            },
            onProcessingCompleted: (path){
              this.path = path;
            },
            onComplete: (){
              setState((){
                isProcessing = false;
                complete = null;
              });
              print('complete');
            }
          );
        }
      });
    } 
    on PlatformException catch (e) {
      print('Unsupported operation Select: $e');
    } 
    catch (e) {
      print('Select: $e');
    }
  }
