Extend the InserterBase and provide you own LineConverter method:
class MyOtherInserter extends InserterBase {
MyOtherInserter({
required this.files,
required this.builders,
}) : super({
buffer: StringBuffer(), // typically, allow injecting this for testing.
readLines: (file) {
/// .... not a real method
return Stream.fromFile(file);
}
});
