如何在[Flutter]中打开PDF或Word文档

问题描述

问题很简单，我想使用Flutter通过默认应用打开任何pdf或doc文件.

Question is simple, I would like to open any pdf or doc file via default App with using Flutter.

请考虑一个与我的pdf资产相关的升高"按钮，当用户按下它时，将通过Acrobat Reader等打开pdf.我不想为此使用任何web_view.

Think a Raised button that related my pdf asset, when user press it, pdf will be opened via Acrobat reader or etc. I don't want to use any web_view for it.

Flutter支持吗?

is it supported in Flutter?

推荐答案

您可以通过在网络浏览器中打开google文档来做到这一点:

You can do this by opening google docs in a web browser :

在pubspec.yaml中，您需要:

In pubspec.yaml you need :

url_launcher: ^0.4.2+5

包括:

import 'package:flutter/src/gestures/tap.dart';
import 'package:url_launcher/url_launcher.dart';

代码段:

new RichText(
  text: new LinkTextSpan(
      url: 'http://docs.google.com/viewer?url=http://www.pdf995.com/samples/pdf.pdf',
      text: 'Show My Pdf'),
),

LinkTextSpan类:

LinkTextSpan class :

class LinkTextSpan extends TextSpan {
  LinkTextSpan({TextStyle style, String url, String text})
      : super(
      style: style,
      text: text ?? url,
      recognizer: new TapGestureRecognizer()
        ..onTap = () {
          launch(url);
        });
}
