To iterate over values in a map in Dart, you can use the values property along with a for loop or the forEach method. This allows you to access each value in the map.
We can iterate over values in a map in Dart using a for loop with the values property, which provides a convenient syntax for iterating over all values in the map.
For example,
myMap
with some key-value pairs. In this example, the map has string keys and integer values.values
property to get an iterable of the values in the map.print
function to verify that we are iterating over all values.void main() {
// Declare and initialize a map
Map<String, int> myMap = {
'one': 1,
'two': 2,
'three': 3
};
// Iterate over values using for loop
for (int value in myMap.values) {
print(value);
}
}

We can iterate over values in a map in Dart using the forEach method, which provides a flexible way to access each value in the map.
For example,
myMap
with some key-value pairs. In this example, the map has string keys and integer values.forEach
method to iterate over the key-value pairs in the map.forEach
, we access each value.print
function to verify that we are iterating over all values.void main() {
// Declare and initialize a map
Map<String, int> myMap = {
'one': 1,
'two': 2,
'three': 3
};
// Iterate over values using forEach method
myMap.forEach((key, value) {
print(value);
});
}

We can store values in a separate list and then iterate over the list in Dart, which provides a way to work with values independently of their keys.
For example,
myMap
with some key-value pairs. In this example, the map has string keys and integer values.values
to store the values from the map.values
property to get an iterable of the values in the map and convert it to a list using the toList
method.values
list and print each value to the console using the print
function to verify that we have stored all values separately.void main() {
// Declare and initialize a map
Map<String, int> myMap = {
'one': 1,
'two': 2,
'three': 3
};
// Store values in a separate list
List<int> values = myMap.values.toList();
// Iterate over the values list
for (int value in values) {
print(value);
}
}
