Answer 1

You can use package https://pub.dev/packages/esys_flutter_share
full example code https://github.com/esysberlin/esys-flutter-share/blob/master/example/lib/main.dart
You can convert file to Uint8List then share with Share.files
code snippet
Future<void> _shareMixed() async {
try {
final ByteData bytes1 = await rootBundle.load('assets/image1.png');
final ByteData bytes2 = await rootBundle.load('assets/image2.png');
final ByteData bytes3 = await rootBundle.load('assets/addresses.csv');
await Share.files(
'esys images',
{
'esys.png': bytes1.buffer.asUint8List(),
'bluedan.png': bytes2.buffer.asUint8List(),
'addresses.csv': bytes3.buffer.asUint8List(),
},
'*/*',
text: 'My optional text.');
} catch (e) {
print('error: $e');
}
}

This function is easy work with gmail share and image file is also open. But problem with social media share like when 4 to 5 image share with whatsup share. Image list show like file image. Help about exact solution and easy share with whatsup image.
Use below code :
Future<void> _shareMixed() async {
try {
final ByteData bytes1 = await rootBundle.load('assets/images/ic_back.svg');
final ByteData bytes2 = await rootBundle.load('assets/images/ic_back.svg');
final ByteData bytes3 = await rootBundle.load('assets/images/ic_back.svg');
await Share.files(
'esys images',
{
'back1.png': bytes1.buffer.asUint8List(),
'back2.png': bytes2.buffer.asUint8List(),
'back3.png': bytes3.buffer.asUint8List(),
},
'*/*',
text: 'My optional text.');
} catch (e) {
print('error: $e');
}
}
