Flutter 实现pdf、word、excel、png、ppt等文件预览功能

在开发过程中,我们很少会遇到预览pdf、word、excel、png、ppt等文件的功能,但是很巧的本人就遇到了,由于第一次使用这个功能,着实是让人挠头啊,最后终于得到解决。

其实实现预览功能很简单,Flutter的插件库就为我们提供了很好的插件

flutter_full_pdf_viewer: ^1.0.1

官网给的文件

import 'dart:async';
import 'dart:io';

import 'package:flutter/foundation.dart';
import 'package:flutter/material.dart';
import 'package:flutter_full_pdf_viewer/full_pdf_viewer_scaffold.dart';
import 'package:path_provider/path_provider.dart';

void main() {
  runApp(MaterialApp(
    title: 'Plugin example app',
    home: MyApp(),
  ));
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State {
  String pathPDF = "";

  @override
  void initState() {
    super.initState();
    createFileOfPdfUrl().then((f)
