Hello, i have problem. I have to connect with MySQL so i want use "sqljocky5" lib but if i add this lib to main.dart then i cant create new Row() creating layouts.

This is code

[code]

import 'package:flutter/material.dart';
import 'package:sqljocky5/sqljocky.dart';


void main(){
  runApp(new MaterialApp(
    home: new MyApp(),
  ));
}

class MyApp extends StatefulWidget{
  @override
  _State createState() => new _State();
}

class _State extends State<MyApp>{

  @override
  Widget build(BuildContext content){

    return new Scaffold(
      appBar: new AppBar(
        title: new Text("PZW Alarm"),
      ),
      body: new Container(
        padding: new EdgeInsets.all(32.0),
        child: new Center(
          child: new Column( 
            children: <Widget>[
              new Text("Typ alarmu: "),
              new Row(), // <- Here is Error
            ],
          ),
        )
      ),
    );
  }
}

[/code]

And this is Error:

[code]

The constructor returns type 'dynamic' that isn't of expected type 'Widget'.

The name 'Row' is defined in the libraries 'basic.dart' and 'row.dart'.

[/code]

If i delete "import 'package:sqljocky5/sqljocky.dart';"then everything i back normal.

The for help.

Hi Paweł,

This is a Dart import problem that is easily solved:

import 'package:sqljocky5/sqljocky.dart' as sqljockey;

Then, when you need to use the Row from sqljockey:

sqljockey.Row row = new sqljockey.Row(...);

There's more information on this here.

Hope that helps,

-Greg.
