I am currently having a few difficulties with ReorderableListView.
I have a list of ToDoPrefabs, which I want to output, because my list does not consist of strings but something else, I get errors in the index, for the key and the text.
this is the error:
"type 'To Prefab' is not a subtype of type 'int'"
I suspect that this is the key. It is also logical since todoprefab is not an int. Does anyone have an idea how I can get another index of the type int in my ReorderableListView
This is my ReorderableListView
return ReorderableListView(
onReorder: _onReorder,
scrollDirection: Axis.vertical,
padding: const EdgeInsets.symmetric(vertical: 8.0),
children: [
for(final item in toDoManagerClass.todoBank)
todocardprefab(item)
]
);
the todocardprefab (not the list)
todocardprefab(var key){
return Dismissible(
key: ValueKey(key),
background: Container(color: Colors.red, alignment: Alignment.centerLeft, child: Icon(Icons.delete),),
secondaryBackground: Container(color: Colors.green, alignment: Alignment.centerRight, child: Icon(Icons.archive),),
child: Card(
child: ListTile(
//leading: Icon(Icons.check_box_outline_blank),
title: Text(toDoManagerClass.todoBank[key].toDoText),
onTap: (){},
),
),
);
}
and this is the simple list.
class ToDoManagerClass{
List<ToDoPrefab> todoBank = [
ToDoPrefab(text: 'Homework', f: false),
ToDoPrefab(text: 'Homework1', f: false),
ToDoPrefab(text: 'Homework12', f: false),
ToDoPrefab(text: 'Homework123', f: false),
ToDoPrefab(text: 'Homework1234', f: false),
ToDoPrefab(text: 'Homework12345', f: false),
];
}
This method should work:
Your reordable listview
return ReorderableListView(
onReorder: _onReorder,
scrollDirection: Axis.vertical,
padding: const EdgeInsets.symmetric(vertical: 8.0),
children: [
for(final item in toDoManagerClass.todoBank)
todocardprefab(item, index())
]
);
and here the function. It returns a number higher with each call.
int index(){
if(i < toDoManagerClass.todoBank.length){
print(i);
i++;
}
return i-1;
}
now you only have to use the index instead of the item in your todocard
