I'd like to know how I can connect the Epson ePOS SDK to Android using Flutter.

From what I've learned, the SDK isn't available for download and installation in my project. Therefore, I need to write Android natively using AndroidManifest.xml, res/xml/device_filter.xml, and build.gradle

The details are as follows:

AndroidManifest.xml

<meta-data
  android:name="io.flutter.embedding.android.NormalTheme"
  android:resource="@style/NormalTheme"
/>
<intent-filter>
   <action android:name="android.intent.action.MAIN"/>
   <action android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED" />
   <category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
   <meta-data android:name="android.hardware.usb.action.USB_DEVICE_ATTACHED"
   android:resource="@xml/device_filter" />

android/res/xml/device_filter.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <usb-device vendor-id="1208" />
</resources>

and android/app/build.gradle

dependencies {
    implementation "androidx.core:core-ktx:1.6.0"
    implementation 'com.epson.epos2:epos2-android:5.15.0'
}

I'd like to know what I should do next to integrate the SDK into Android using Flutter.

I studied the documentation attached below and used chatGPT to help me a little.

If you guys can help me, I would appreciate it, and thanks in advance for your answers.

  • Unclear if you've seen: docs.flutter.dev/platform-integration/platform-channels however StackOverflow is for specific questions generally with code / error logs. Note: Why is "Can someone help me?" not a useful question? Commented Sep 1 at 11:11
  • Thank you for your comment. I'll try using Flutter platform-channel. And thanks again for the tips on how to post. This is my first time posting, and it's very helpful. I'll try to post better in the future. Commented Sep 2 at 2:58
  • Hi from where did you get. implementation 'com.epson.epos2:epos2-android:5.15.0' I've been looking around for an SDK online but all documents do not point to an actual sdk Commented Sep 4 at 14:32
