flutter_file_view's Issues

安卓经常出现插件下载失败，插件初始化失败，重新初始化也没用

重新调用FlutterFileView.init()

No one maintains it?

Because flutter_file_view 2.2.1 depends on dio ^4.0.0 and no versions of flutter_file_view match >2.2.1 <3.0.0, flutter_file_view ^2.2.1 requires dio ^4.0.0.
So, because project depends on both flutter_file_view ^2.2.1 and dio ^5.4.1, version solving failed.

Error!!! Files does not open

I have tried everything, yet I keep getting this issue, for all file type. Pls is there something I'm missing?

Error: The getter 'titleMedium' isn't defined for the class 'TextTheme'.

Error: The getter 'bodyMedium' isn't defined for the class 'TextTheme'.

• 'TextTheme' is from 'package:flutter/src/material/text_theme.dart' ('../../flutter/packages/flutter/lib/src/material/text_theme.dart').
  Try correcting the name to the name of an existing getter, or defining a getter or field named 'bodyMedium'.
  style: widget.fileSizeStyle ?? Theme.of(context).textTheme.bodyMedium,

新版本tbs怎么适配

因为44085版本的tbs有访问imsi导致华为审核不过，但是我把tbs升级到最新的44226应用安装就闪退，怎么在gradle中配置呢，请教下

Unable display file on Android

Even though every setup is done correctly, on Android it says Non-existent file.

Here is my code

FileViewController? controller = FileViewController.asset(filePath!);

Navigator.of(context).push(
                      MaterialPageRoute<void>(
                        builder: (_) => FileViewer(
                          fileName: fileName,
                          controller: controller!,
                        ),
                      ),
                    );

file_viewer.dart

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

import 'components.dart';

class FileViewer extends StatelessWidget {
  const FileViewer({Key? key, required this.fileName, required this.controller}) : super(key: key);

  final String fileName;
  final FileViewController controller;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Colors.white,
        leading: GestureDetector(
          onTap: () => Navigator.pop(context),
          child: Icon(Icons.adaptive.arrow_back, color: kPrimaryColor),
        ),
        title: Tooltip(
          message: fileName,
          child: Text(fileName, style: kTextSubtitle2),
        ),
      ),
      backgroundColor: kBackgroundColor,
      body: FileView(
        controller: controller,
      ),
    );
  }
}

Here is output on Android (real device, not emulator)

This is output on iOS simulator

If I did something wrong please correct me, if there is a bug on Android site I look forward fix that bug soon!

Is this package still under maintenance?

When I load flutter_file_view in pubspec.yaml, it obviously prompts that the dio package in flutter_file_view is too low.

Because flutter_file_view >=2.0.3 depends on dio ^4.0.0 and wolkezoo_app depends on dio ^5.3.3, flutter_file_view >=2.0.3 is forbidden.
So, because wolkezoo_app depends on flutter_file_view ^2.2.1, version solving failed.

X5Status.download_fail

Hi can you please guide me about this why x5 download is failed

获取文件大小失败

不知道我的描述是否准确，通过nginx映射到的文件是可以正常获取到文件大小的，当我的文件链接是alioss或者经后端的时候是获取失败的。 具体文件如下

2.0.8运行出错

flutter_file_view-2.0.8+3/android/src/main/kotlin/com/file/view/LocalFileViewer.kt: (109, 45): Type mismatch: inferred type is Boolean? but Boolean was expected

Engine loading failed, please restart the App

word文档下载后乱码

NetworkFileViewer(
downloadUrl: downloadUrl,
downloadPath: downloadPath,
onViewPressed: () {
push(LocalFileViewerPage(downloadPath));
},
));
下载word文件后，文件内容乱码，需要加什么参数吗？

Not supported by playstore?

When this plugin is not supported by playstore then what is use of this plugin?

你这插件不稳定呀

插件不稳定呀，动不动初始化的时候就报错，内核初始化失败，包括demo也报错了

Unable to support android

Please set the platform availability only IOS, don't just put at the bottom remarks, thank you
However, in iOS it works very well.

file exists, but plugin says it is non-existant.

I am using this plugin to display files that I have downloaded using http get and saved to local storage. When I give the plugin the directory to look in it says that the file doesn't exist. The path I'm saving the file to looks like this

/Users/myuser/Library/Developer/CoreSimulator/Devices/BD738457-C105-43FE-A38A-60B401052DDC/data/Containers/Data/Application/AA3FCA19-D06E-4129-917F-39032F261F0C/Documents/67c1dcdf-aea7-406e-a7c6-79f685061751.pdf

the file does exist there and I can open it, but the simulator can't.
