Error trying to retrieve local directory to write file. #7

Open leonardopaim opened 5 years ago

leonardopaim commented 5 years ago

I am Brazilian and I used google translator translation for this request:

I am trying to render a PDF on my App Flutter screen and at the moment the getApplicationDocumentsDirectory() method is called on the first line of loadPdf() the error described below is being returned.

In some attempts to get around the problem I saw that this method only returns the error when I have lib pdf_viewer_plugin imported into my project. If this lib is not imported the getApplicationDocumentsDirectory() method that is part of path_provider works normally.

(Device model used in development: Xiaomi Mi A1)

CODE:

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:path_provider/path_provider.dart';
import 'package:pdf_viewer_plugin/pdf_viewer_plugin.dart';

void main() {
  runApp(App());
}

class App extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      theme: ThemeData(
        primarySwatch: Colors.indigo,
        primaryColor: Colors.blue,
      ),
      title: "Title App",
      home: NFCePage(),
    );
  }
}

class NFCePage extends StatefulWidget {
  @override
  _NFCePageState createState() => _NFCePageState();
}

class _NFCePageState extends State<NFCePage> {
  String pathPdf = "";

  @override
  void initState() {
    super.initState();
    loadPdf();
  }

  void loadPdf() async {
    final directory = await getApplicationDocumentsDirectory();
    final path = directory.path;
    final file = File('$path/nfce.pdf');
    ByteData bd = await rootBundle.load('assets/nfce.pdf');
    file.writeAsBytes(bd.buffer.asUint8List());

    bool arquivoExiste = await file.exists();
    if (arquivoExiste) pathPdf = file.path;

    if (!mounted) return;

    setState(() {});
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            Expanded(
              child: Container(
                height: 600,
                color: Colors.amber,
                child: PdfViewer(
                  filePath: pathPdf,
                ),
              ),
            ),
          ],
        ),
      ),
    );
  }

  buildPdfViewer() {
    return Container(
      child: PdfViewer(
        filePath: pathPdf,
      ),
    );
  }
}

I was able to work around the issue by changing the widget that surrounds PDFViewer ().

it was like this:

@override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        child: Column(
          mainAxisSize: MainAxisSize.min,
          children: <Widget>[
            path != null
                ? Flexible(
                    fit: FlexFit.loose,
                    flex: 1,
                    child: Container(
                      child: PdfViewer(
                        filePath: path,
                      ),
                    ),
                  )
                : Flexible(
                    fit: FlexFit.loose,
                    flex: 1,
                    child: Container(
                      child: Text("O PDF não está carregado"),
                    ),
                  ),
            listaDeOpcoesMinimalista(),
          ],
        ),
      ),
    );
  }

I didn't understand how the previous mode hampers screen loading. If you have any advice that better my implementation I would be grateful.

@leonardopaim Hey, I saw that your problem is the need for defining a valid path to works, I will try to validate the path before load to fix this.

leonardopaim commented 5 years ago

@lubritto Thank you, I will be waiting for the improvement.

Strange behavior is also happening that I couldn't understand how to solve and I don't know if it's related to the initial problem.

After the file is rendered on screen, if I save the project, causing hot reload to run, the app is giving fatal error.

This issue is affecting a process I have on a screen that comes after viewing the PDF. I want to email the file and ask on another screen for the user to type. As soon as I click on TextFormField, the above behavior happens.

If you know a way this problem does not occur please let me know.
