I am looking for a Flutter developer to help me complete the documentation and publish my app on my developer account. The design is already done, so I just need assistance with the technical aspects of the project. I am flexible with the timeline, so there is no specific deadline for the project. However, I do require user authentication as an important feature for this app. The ideal candidate should have experience with Flutter development and be familiar with publishing on developer accounts.
