A simple top Modal Sheet for flutter

top_modal_sheet

A popup simple topModalSheet menu button widget with handsome design and easy to use.

Installations

Add top_modal_sheet: ^1.0.0 in your pubspec.yaml dependencies. And import it:

import 'package:top_modal_sheet/top_modal_sheet.dart';

How to use

Simply call showModalTopSheet to display it

MaterialButton(
  color: Colors.white,
  elevation: 5,
  child: const Text("Show TopModal"),
  onPressed: () async {
    var value = await showTopModalSheet<String>(context: context, child: DumyModal());

    if(value != null){
      setState(() {
        _topModalData = value;
      });
    }
  },
)

Here is another way to invoke the modal using a Globalkey to get a smooth pop animation

final _topModalSheetKey = GlobalKey<TopModalSheetState>();

MaterialButton(
  color: Colors.white,
  elevation: 5,
  child: const Text("Show TopModal 2"),
  onPressed: () async {
    var value = await Navigator.of(context).push<List<int>>(PageRouteBuilder(pageBuilder: (_, __, ___) {
      return TopModalSheet(
        key: _topModalSheetKey,
        child: Container(color: Colors.teal, height: MediaQuery.of(context).size.height * .2, child: Center(
          child: MaterialButton(
            color: Colors.white,
            child: const Text("Back", style: TextStyle(color: Colors.teal),),
            onPressed: () {
              _topModalSheetKey.currentState.onBackPressed(data: [1,2,3]);
            },
          )
        )),
      );
    }, opaque: false));

    if(value != null){
      setState(() {
        _topModalData = "$value";
      });
    }
  },
)
