final db = MeridianClient(

schema: SchemaDefinition(

'todos': CollectionSchema(fields: {
'id': FieldDef(type: 'string'),
'title': FieldDef(type: 'string'),
'done': FieldDef(type: 'boolean', default: false),
}),
},
),
);
// Reactive query
db.collection('todos').find().listen((todos) {
setState(() => this.todos = todos);
});
