error in MemoryImage not defined in package pdf/widgets.dart-CodePudding

import 'dart:io';
import 'package:flutter/material.dart' as material ;
import 'package:flutter/services.dart';
import 'package:pdf/pdf.dart';
import 'package:pdf/widgets.dart' as pw;


class PdfParagraphApi {
  
  static Future<void> generate(key) async {
    final pdf = pw.Document();
    final img = pw.MemoryImage(await rootBundle.load('assets/img.png')).buffer.asUint8List();
    pdf.addPage(
      pw.MultiPage(
        build: (context) => <pw.Widget>[
          pw.Image(img),
       ]),
    );
  }
}

i'm trying to create a pdf with an image inside it and i'm using the library pdf/widgets.dart to create the image as i found in flutters documentation but i'm facing a problem. the error message is the following : The function 'MemoryImage' isn't defined. Try importing the library that defines 'MemoryImage', correcting the name to the name of an existing function, or defining a function named 'MemoryImage'.dartundefined_function

insert image into pdf not working

CodePudding user response：

Replace pw.MemoryImage with material.MemoryImage, because MemoryImage comes from the painting library, which is included inside the material library.

CodePudding user response：

Try to replace the below import:

import 'package:flutter/material.dart' as material ;

with this import 'package:flutter/material.dart';
