import 'package:sqflite/sqflite.dart';
void createDatabase(){
getDatabasesPath().then((dbPath){
final String path = join(dbPath, 'bytebank.db');
openDatabase(path, onCreate: (db, version){
db.execute('CREATE TABLE contacts('
'id INTEGER PRIMARY KEY, '
'name TEXT, '
'account_number INTEGER)');
}, version: 1);
});
join não compila. Estou usando o android Studio.
