How to debug a Custom Widget loading a flutter plugin/SDK easiest?

Hi all 👋, I want to integrate the "anyline SDK" (www.anyline.com) in my Flutterflow project as a "Custom Widget" so that I can scan barcodes with the camera. For some the app crashes on android every time I try to open the bottom sheet which should load the anyline SDK.

I have the following code:

// Automatic FlutterFlow imports
import '/backend/backend.dart';
import '/backend/schema/structs/index.dart';
import '/flutter_flow/flutter_flow_theme.dart';
import '/flutter_flow/flutter_flow_util.dart';
import '/custom_code/widgets/index.dart'; // Imports other custom widgets
import '/custom_code/actions/index.dart'; // Imports custom actions
import '/flutter_flow/custom_functions.dart'; // Imports custom functions
import 'package:flutter/material.dart';
// Begin custom widget code
// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

import 'package:anyline_plugin/anyline_plugin.dart';

class AnylineScanner extends StatefulWidget {
  const AnylineScanner({
    super.key,
    this.width,
    this.height,
    this.keyAnyline,
    this.config,
  });

  final double? width;
  final double? height;
  final String? keyAnyline;
  final String? config;

  @override
  State<AnylineScanner> createState() => _AnylineScannerState();
}

class _AnylineScannerState extends State<AnylineScanner> {
  late AnylinePlugin _anylinePlugin;

  @override
  void initState() {
    super.initState();
    _initializeSdk();
  }

  Future<void> _initializeSdk() async {
    if (widget.keyAnyline == null) {
      print("Error: License key is null.");
      return;
    }

    _anylinePlugin = AnylinePlugin();
    try {
      await _anylinePlugin.initSdk(widget.keyAnyline!);
      print("Anyline SDK initialized successfully.");
    } catch (error) {
      print("Error initializing Anyline SDK: $error");
    }
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      width: widget.width ?? double.infinity,
      height: widget.height ?? double.infinity,
      // Add your scanner UI or functionality here
    );
  }
}

Maybe I'm doing something super obvious wrong in the code?

Here's more info about the Anyline plugin: https://documentation.anyline.com/flutter-plugin-component/latest/getting-started.html

I'm not sure if I can test whether it works on my desktop, because it uses the camera. On desktop (Test Session) it doesn't crash at least.

On my Android phone I don't know how to debug it best. Where can I find the print() statements for instance?

Haven't tested it on iOS yet.

Thanks for every help or suggestion. 🙏
