pada saat di debuging muncul notice di bawah ini

The plugin qrscan uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

Hallo Sandi,

Kalau dilihat dari output errornya:
```
The plugin qrscan uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding. Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
```
Itu jelas ya sebuah warning terkait penggunaan versi android embeeding yang sudah deprecated pada code di plugin/package dari qrscan.
Nah karena ini merupakan masalah yang berada pada code dari package tersebut, maka tidak ada yang bisa kita lakuin.
dan juga saya lihat package qrscan sudah lumayan lama tidak diupdate. Jadi lebih baik kamu mencari package lain saja yang masih aktif diupdate sama developernya.

Saya barusan coba search dan menemukan package yang lebih baru dan lebih bagus dari package yang kamu pakai nih, bisa dicoba
