Flutter List Filtering with Multiple Conditions
In Flutter, you can filter a list based on multiple conditions using the where
method and =>
syntax.
Let’s consider an example where we have a list of names and we want to filter out the names that start with the letter ‘A’
and contain the letter ‘e’ in them.
List names = ['Alice', 'Bob', 'Charlie', 'Dave', 'Alex', 'Eve'];
void main() {
List filteredNames = names
.where((name) => name.startsWith('A') && name.contains('e'))
.toList();
print(filteredNames); // Output: [Alice, Alex]
}
Here, we define a list of names and use the where
method on that list. Within the where
method,
we provide a lambda function (using =>
syntax) that takes each name from the list as input.
The lambda function checks if the name starts with ‘A’ and contains ‘e’ in it. If both conditions are true,
the name is included in the filtered list.
In the example above, the filteredNames list will contain only the names “Alice” and “Alex” since they meet both conditions.
