This error message occurs when you are trying to assign a value of type List<dynamic>
to a variable that expects a value of type Map<String, dynamic>
.
In Dart, maps are key-value pairs, where each key is of type String
and each value can be of any type, including dynamic
. On the other hand, lists are simply collections of elements of any type, including dynamic
.
To resolve this error, you need to convert the List<dynamic>
value into a Map<String, dynamic>
value. This can be done using the Map.fromIterable
method, which creates a map from a list of key-value pairs. Here’s an example:
List<dynamic> list = [
{"key": "value1"},
{"key": "value2"},
];
Map<String, dynamic> map = Map.fromIterable(list,
key: (item) => "key", value: (item) => item["key"]);
In this example, the Map.fromIterable
method creates a map from the list
where the keys are obtained using the key
function and the values are obtained using the value
function. The resulting map
will be of type Map<String, dynamic>
.
