We need to scan using zebra tc77 but enter event not found at the end of text , even after we have enabled enter key at settings?
_onChangeListener(String val) {
if(val.isEmpty) return;
SystemChannels.textInput.invokeMethod('TextInput.hide');
Log.d("onChange $val");
Log.d("Last char as int ${val.codeUnitAt(val.length -1)}");
setState(() {
logs.add("Scanned data : $val, length : ${val.length}");
logs.add("Last char as int ${val.codeUnitAt(val.length -1)}");
if(val.codeUnitAt(val.length -1) == 13){
logs.add("Enter key found as logical key (13)");
} else {
logs.add("Enter key not found as logical key");
}
if(val.contains('\n') || val.contains('\r')){
logs.add("Enter key found as character");
} else {
logs.add("Enter key not found as character");
}
});
return;
}
i have used rawkeyboardlistener to get scan event
RawKeyboardListener(
onKey:(RawKeyEvent event) {
String e = event.character ?? '';
if (e.isNotEmpty && isValid(e) || e == '-') {
Log.d("Shelf Data ${e}");
scanData += e;
}
if (e == '\n' || e == '\r') {
Log.d("Entered Shelf");
scanShelfTextField.clear();
});
}
})
