Methods

camelCaseKeys<V>() → Map<String, V>
Camel case all keys in the map. Returns a new map with camel cased keys.
camelCaseValues<K>() → Map<K, String>
Camel case all values in the map. Returns a new map with camel cased values.
capitalizeKeys<V>() → Map<String, V>
Capitalize all keys in the map. Returns a new map with capitalized keys.
capitalizeValues<K>() → Map<K, String>
Capitalize all values in the map. Returns a new map with capitalized values.
contains(Object key, Object value) → bool
Returns true if the map contains the specified key and value, false otherwise.
filter<K, V>(bool predicate(K key, V value)) → Map<K, V>
Returns a new map with all entries that satisfy the given predicate. The entries in the resulting map preserve the order of the original map.
filterEmpty<K, V>() → Map<K, V>
Filter empty values from the map. Returns a new map with non-empty values.
filterKeys<K, V>(Iterable<K> keys) → Map<K, V>
Filter where the key is in the given keys. Returns a new map with filtered entries.
filterNot<K, V>(bool predicate(K key, V value)) → Map<K, V>
Returns a new map with all entries that satisfy the given predicate. The entries in the resulting map do not preserve the order of the original map.
filterNull<K, V>() → Map<K, V>
Filter null values from the map. Returns a new map with non-null values.
filterValues<K, V>(Iterable<V> values) → Map<K, V>
Filter where the value is in the given values. Returns a new map with filtered entries.
kebabCaseKeys<V>() → Map<String, V>
Kebab case all keys in the map. Returns a new map with kebab cased keys.
kebabCaseValues<K>() → Map<K, String>
Kebab case all values in the map. Returns a new map with kebab cased values.
partition<K, V>(bool predicate(K key, V value)) → Pair<Map<K, V>, Map<K, V>>
Split map into two maps based on the predicate. Returns a list of two maps.
prefixKeys<V>(String prefix) → Map<String, V>
Add prefix to all keys in the map. Returns a new map with prefixed keys.
prefixValues<K>(String prefix) → Map<K, String>
Add prefix to all values in the map. Returns a new map with prefixed values.
printDebug<K, V>({String label = 'Map', String separator = ': ', String indent = ' '}) → void
debug print the map with label and separator. label is the label for the map. separator is the separator between key and value. indent is the indent for each line.
reject<K, V>(bool predicate(K key, V value)) → Map<K, V>
Returns a new map with all entries that do not satisfy the given predicate. The entries in the resulting map preserve the order of the original map.
rejectKeys<K, V>(Iterable<K> keys) → Map<K, V>
Filter where the key is not in the given keys. Returns a new map with filtered entries.
rejectNot<K, V>(bool predicate(K key, V value)) → Map<K, V>
Returns a new map with all entries that do not satisfy the given predicate. The entries in the resulting map do not preserve the order of the original map.
rejectValues<K, V>(Iterable<V> values) → Map<K, V>
Filter where the value is not in the given values. Returns a new map with filtered entries.
removeExact({required Object key, required Object value}) → bool
Returns true if the map contains the specified key and value and removes the entry, false otherwise.
shift<K, V>() → MapEntry<K, V>
Shift the first entry from the map.
snakeCaseKeys<V>() → Map<String, V>
Snake case all keys in the map. Returns a new map with snake cased keys.
snakeCaseValues<K>() → Map<K, String>
Snake case all values in the map. Returns a new map with snake cased values.
suffixKeys<V>(String suffix) → Map<String, V>
Add suffix to all keys in the map. Returns a new map with suffixed keys.
suffixValues<K>(String suffix) → Map<K, String>
Add suffix to all values in the map. Returns a new map with suffixed values.
uniqueValues<K, V>() → Map<K, V>
Remove duplicate values from the map. Returns a new map with unique values.
