At AppTree, we recently made the jump to Flutter to replace our existing iOS and Android applications. A major part of our application is mapping.
Flutter is still in alpha and as such, still has functional areas yet to be completely built out. However we find Flutter to be so useful that we prefer to fill any gaps ourselves rather than waiting to adopt it when it’s fully matured. Fortunately, the Flutter team has come up with a great solution by allowing early adopters to build plugins.
