本文翻译自 open_file | Flutter Package (pub.dev)

该插件在 Flutter 中用字符串来调用原生应用来打开文件。 支持 iOS(DocumentInteraction) / android(intent) / PC(ffi) / web(dart:html)

使用

要使用该插件，需要在 pubspec.yaml 中添加依赖。

dependencies:
  #androidx
  open_file: ^lastVersion 
  #support
  #open_file: ^1.3.0

示例

import 'package:open_file/open_file.dart';

OpenFile.open("/sdcard/example.txt");
//OpenFile.open("/sdcard/example.txt", type: "text/plain", uti: "public.plain-text");

如果和其它的有关 FileProvider 的插件冲突，在 /android/app/src/main/AndroidManifest.xml 中添加下面的代码

<manifest xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" package="xxx.xxx.xxxxx">
    <application>
        ...
        <provider android:name="androidx.core.content.FileProvider" android:authorities="${applicationId}.fileProvider" android:exported="false" android:grantUriPermissions="true" tools:replace="android:authorities">
            <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/filepaths" tools:replace="android:resource" />
        </provider>
    </application>
</manifest>

当 Androird 依赖 ‘com.android.support:appcompat-v7’ 有不同版本的编译错误时，在 /android/build.gradle 添加下面的代码

subprojects {
    project.configurations.all {
        resolutionStrategy.eachDependency { details ->
            if (details.requested.group == 'com.android.support'
                    && !details.requested.name.contains('multidex') ) {
                details.useVersion "27.1.1"
            }
        }
    }
}

IOS 使用 UTI (DocumentInteraction Auto)

{
            {".rtf",    "public.rtf"},
            {".txt",    "public.plain-text"},
            {".html",   "public.html"},
            {".htm",    "public.html"},
            {".xml",    "public.xml"},
            {".tar",    "public.tar-archive"},
            {".gz",     "org.gnu.gnu-zip-archive"},
            {".gzip",   "org.gnu.gnu-zip-archive"},
            {".tgz",    "org.gnu.gnu-zip-tar-archive"},
            {".jpg",    "public.jpeg"},
            {".jpeg",   "public.jpeg"},
            {".png",    "public.png"},
            {".avi",    "public.avi"},
            {".mpg",    "public.mpeg"},
            {".mpeg",   "public.mpeg"},
            {".mp4",    "public.mpeg-4"},
            {".3gpp",   "public.3gpp"},
            {".3gp",    "public.3gpp"},
            {".mp3",    "public.mp3"},
            {".zip",    "com.pkware.zip-archive"},
            {".gif",    "com.compuserve.gif"},
            {".bmp",    "com.microsoft.bmp"},
            {".ico",    "com.microsoft.ico"},
            {".doc",    "com.microsoft.word.doc"},
            {".xls",    "com.microsoft.excel.xls"},
            {".ppt",    "com.microsoft.powerpoint.​ppt"},
            {".wav",    "com.microsoft.waveform-​audio"},
            {".wm",     "com.microsoft.windows-​media-wm"},
            {".wmv",    "com.microsoft.windows-​media-wmv"},
            {".pdf",    "com.adobe.pdf"}
