Flutter Printing Package: Create pdf table with loop

Question

I want to create a pdf document with the package 'pdf'. The example on the dart - page is working fine: https://pub.dev/packages/pdf#-example-tab-

You can see that the table is static. I want to create a dynamic table in the pdf document.

The columns will be constant, but the rows have to be dynamic.

I have tried to insert a for() - loop.

The syntax is not correct.

      pdfWidget.Table.fromTextArray(context: context, data: <List<String>> [
        <String>['Date', 'PDF Version', 'Acrobat Version'],
        //.....
        //more Strings here.....
      ]),

Solution

I ran into the same issue. This seemed to work for me.

pdf.addPage(
  MultiPage(
    build: (context) => [
      Table.fromTextArray(context: context, data: <List<String>>[
        <String>['Msg ID', 'DateTime', 'Type', 'Body'],
        ...msgList.map(
            (msg) => [msg.counter, msg.dateTimeStamp, msg.type, msg.body])
      ]),
    ],
  ),
);

where my msgList object was a custom List, ie: List<SingleMessage>
