Flutter Map String Dynamic To List

On the previous page, the user enters the amount the purchase will be, for example, $3,500. To convert each element in the map to a string, tostring () is used. Flutter hwo to cast dynamic list ot list of string.

I am trying to write correctly flutter by precising specific types. Get index of element in map dart mylist.asmap().entries.map((entry) { int idx = entry.key; Flutter list> example //flutter list<<strong>map</strong> < string, object > > example // this is a simple example to show how you can use a list // with a number of widgets, ideally you should split your classes into // separate files in order to trim down you widget tree.

Creating our main myapp extends statelesswidget class.

Type 'list<<strong>map</strong><<strong>string</strong>, object>>' is not a subtype of type 'list<<strong>map</strong><<strong>string</strong>, int>>' in type cast. Map () is used to iterate over a list of dynamic strings. Here, in dart map, a key & value can be of any datatype, it means that we can store any data type because a map in dart language is a dynamic collection of data/information. See frank's answer below that is the correct one for the latest version of the firebase_database package.
