Creating a PDF with table having dynamic rows in Flutter - flutter

Question

I want to make a dynamic table with list contents. I am not able to map the array list with the List type of table data. I am not getting table in PDF and instead it's showing me an error.
This is my PDF code:
goTocreatePdf(context,AllTranList) async {
final Document pdf = Document();
pdf.addPage(MultiPage(
pageFormat:
PdfPageFormat.letter.copyWith(marginBottom: 1.5 * PdfPageFormat.cm),
crossAxisAlignment: CrossAxisAlignment.start,
header: (Context context) {
if (context.pageNumber == 1) {
return null;
}
return Container(
alignment: Alignment.centerRight,
margin: const EdgeInsets.only(bottom: 3.0 * PdfPageFormat.mm),
padding: const EdgeInsets.only(bottom: 3.0 * PdfPageFormat.mm),
decoration: const BoxDecoration(
border:
BoxBorder(bottom: true, width: 0.5, color: PdfColors.grey)),
child: Text('Report',
style: Theme.of(context)
.defaultTextStyle
.copyWith(color: PdfColors.grey)));
},
footer: (Context context) {
return Container(
alignment: Alignment.centerRight,
margin: const EdgeInsets.only(top: 1.0 * PdfPageFormat.cm),
child: Text('Page ${context.pageNumber} of ${context.pagesCount}',
style: Theme.of(context)
.defaultTextStyle
.copyWith(color: PdfColors.grey)));
},
build: (Context context) => <Widget>[
Header(
level: 0,
child: Row(
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Text('TRANSACTION LIST', textScaleFactor: 2),
PdfLogo()
])),
Header(level: 1, text: 'What is Lorem Ipsum?'),
Table.fromTextArray(context: context, data: <List<String>>[
<String>[ 'TRANSACTION_AMOUNT No', 'CUSTREF_ID',
'REMARKS','PAYEE_VIR_ID','PAYER_VIR_ID'],
...AllTranList.map(
(item) => [item.TRANSACTION_AMOUNT,
item.CUSTREF_ID,item.REMARKS,item.PAYEE_VIR_ID,item.PAYER_VIR_ID])
]),
//save PDF
final String dir = (await getApplicationDocumentsDirectory()).path;
final String path = '$dir/report.pdf';
Dio dio = new Dio();
final File file = File(path);
await file.writeAsBytes(pdf.save());
material.Navigator.of(context).push(
material.MaterialPageRoute(
builder: (_) => PdfViewerPage(path: path),
),
);
}
Also I am not able to save PDF in the external storage.
This is the AllTransitList that I am mapping:
[{TRANSACTION_AMOUNT: 1.00,
CUSTREF_ID: 001819655570,
CREATED_ON: 2020-01-18T19:55:40.412Z,
REMARKS: SUCCESS,
RESPONSE: SUCCESS,
PAYEE_VIR_ID: navyabj#fbl,
PAYER_VIR_ID: abinthomas0073#oksbi},
{TRANSACTION_AMOUNT: 1.00,
CUSTREF_ID: 002218989414,
CREATED_ON: 2020-01-22T18:12:13.500Z,
REMARKS: SUCCESS,
RESPONSE: SUCCESS,
PAYEE_VIR_ID: navyabj#fbl,
PAYER_VIR_ID: abinthomas0073#oksbi},
{TRANSACTION_AMOUNT: 30.00,
