Flutter Share package causing not helpful error












0















I am trying to use the Share package provided by the Flutter team. I tried implementing the package and when that didn't work I tried straight up copying and pasting their code, but got an error just the same. Unfortunately the error is not very helpful and the description of the error says "we need to explain this better". Any ideas?



Here's the package I'm using



My Code:



FlatButton(
child: Text(
'Share',
style: TextStyle(
color: Color.fromRGBO(245, 93, 62, 1.0)),
),
color: Colors.grey[100],
onPressed: () {
final RenderBox box = context.findRenderObject();
Share.share('Hello this is a test',
sharePositionOrigin:
box.localToGlobal(Offset.zero) &
box.size);
},
),


The Error:



flutter: The following assertion was thrown while handling a gesture:
flutter: type 'RenderSliverList' is not a subtype of type 'RenderBox'
flutter:
flutter: Either the assertion indicates an error in the framework itself, or we should provide substantially

  • This peace of code is working fine in both android and iOS I think the problem coming from somewhere else inside your code

The issue in this line



RenderBox box = context.findRenderObject();


the right side return RenderSliverList and you assigning it to RenderBox that why there is a mismatch type.

You need to extract share button into its own widget. Try the following complete code. It works.

The issue in this line



RenderBox box = context.findRenderObject();


the right side return RenderSliverList and you assigning it to RenderBox that why there is a mismatch type.



What excactly you are trying to share? so I can help with that



Edit:



You need to extract share button into its own widget. Try the following complete code. It works.



  import 'package:flutter/material.dart';
import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

@override
State<StatefulWidget> createState() {
// TODO: implement createState
return _EverythingState();
}
}

class _EverythingState extends State<Everything> {
Widget _buildEventCards(BuildContext context, DocumentSnapshot document) {
var width = MediaQuery.of(context).size.width;

return Container(
padding: EdgeInsets.symmetric(vertical: 10.0, horizontal: 14.0),
