如何在whatsapp上以动态方式分享图像和文本

Question

我无法在whatsapp上共享文本和图像，因为如果一开始我只有文本，则只能共享文本，我该如何解决。我正在使用easy flutter share插件。或者我可以检查在活动视图中选择了哪个应用程序。

您可以使用Flutter_share软件包https://pub.dev/packages/flutter_share

示例：

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

import 'package:flutter/services.dart';
import 'package:flutter_share/flutter_share.dart';
import 'package:documents_picker/documents_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  Future<void> share() async {
    await FlutterShare.share(
      title: 'Example share',
      text: 'Example share text',
      linkUrl: 'https://flutter.dev/',
      chooserTitle: 'Example Chooser Title'
    );
  }

  Future<void> shareFile() async {
    List<dynamic> docs = await DocumentsPicker.pickDocuments;
    if (docs == null || docs.isEmpty) return null;

    await FlutterShare.shareFile(
      title: 'Example share',
      text: 'Example share text',
      filePath: docs[0] as String,
    );
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Plugin example app'),
        ),
        body: Center(
          child: Column(
            crossAxisAlignment: CrossAxisAlignment.center,
            mainAxisAlignment: MainAxisAlignment.center,
            children: <Widget>[
              FlatButton(
                child: Text('Share text and link'),
                onPressed: share,
              ),
              FlatButton(
                child: Text('Share local file'),
                onPressed: shareFile,
              ),
            ],
          ),
        ),
      ),
    );
  }
}
