Can't get the example working

[daybson]

I can't get the code to works. I'm able to draw a list, but it's not dragging items...
Here's my code:

import 'package:boardview/board_item.dart';
import 'package:boardview/board_list.dart';
import 'package:boardview/boardview.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class MyView extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return MyViewState();
  }
}

class MyViewState extends State<MyView> {
  @override
  Widget build(BuildContext context) {
    var boardItem0 = BoardItem(
        item: Container(
            height: 8,
            child: Text(
              'TESTE 0',
              style: TextStyle(fontSize: 12),
            )));
    var boardItem1 = BoardItem(
        item: Container(
            width: double.maxFinite,
            height: 10,
            child: Text(
              '  TESTE 1   ',
              style: TextStyle(fontSize: 12),
            )));

    var listBoardItems = List<BoardItem>();
    listBoardItems.add(boardItem0);
    listBoardItems.add(boardItem1);

    var boardList = BoardList(
        backgroundColor: Colors.yellow,
        items: listBoardItems,
        index: 0,
        footer: Container(height: 50));

    var listBoardListItems = List<BoardList>();
    listBoardListItems.add(boardList);

    var boardView0 = BoardView(lists: listBoardListItems);

    return Container(
      child: boardView0,
    );
  }
}

Are the BoardItems not draggable or is it the BoardList? BoardList are draggable from a header widget and I don't see one on yours. So try adding something like header: Container(height: 50,), to it

The BoardItems are not draggable.
I've atacched a gif with the result of the code above:

I tested the above code and it seems to work. I see in your picture that you have an ad in it. Do you also have a Stack or something that would be blocking any touches to the BoardView?

I've got it!

But there's a small issue: if I click and drag immediately, it doesn't drag at all. I have to pressure for a some time and then drag. Could be the Android Emulator slowing down the UI?

import 'package:boardview/board_item.dart';
import 'package:boardview/board_list.dart';
import 'package:boardview/boardview.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';

class MyView extends StatefulWidget {
  @override
  State<StatefulWidget> createState() {
    return MyViewState();
  }
}

class MyViewState extends State<MyView> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          mainAxisAlignment: MainAxisAlignment.start,
          children: <Widget>[
            Expanded(
                child: BoardView(
              lists: _get() + _get(),
            )),
          ]),
    );
  }

  List<BoardList> _get() {
    var boardItem0 = BoardItem(
        item: Container(
            height: 20,
            color: Colors.indigo[100],
            child: Text(
              'ABC',
              style: TextStyle(fontSize: 12),
            )));
    var boardItem1 = BoardItem(
        item: Container(
            height: 20,
            color: Colors.purple[100],
            child: Text(
              '123',
              style: TextStyle(fontSize: 12),
            )));

    var listBoardItems = List<BoardItem>();
    listBoardItems.add(boardItem0);
    listBoardItems.add(boardItem1);

    var boardList = BoardList(
        headerBackgroundColor: Colors.green,
        header: Container(
          height: 50,
          color: Colors.blue,
        ),
        items: listBoardItems,
        footer: Container(
          height: 50,
          color: Colors.red,
        ));

    var listBoardListItems = List<BoardList>();
    listBoardListItems.add(boardList);

    return (listBoardListItems);
  }
}

Awesome! I use onLongPress to detect a drag which I think takes around 1000ms to trigger. I might change it to be customizable in the future though.
