Troubleshooting Dynamic Text Field Display in Flutter

When developing applications with Flutter, you may come across a situation where you need to pass multiple values from text fields on one screen to another. A common challenge is ensuring that all values are passed correctly rather than just the last one. In this post, we’ll address a specific problem related to this workflow and provide a clear solution.

The Problem

While navigating between screens in Flutter, developers may encounter a scenario where only the last value from a dynamic list of text fields is displayed on the next screen. This is often due to how the navigator handles screen transitions and the way values are extracted from text controllers during the navigation process.

To illustrate, consider a loop intended to collect values from a list of text field controllers:

Here, the navigation will replace the current screen with the preview screen but will not retain previous values, resulting in the display of just one text field value instead of all.

The Solution

Here's How to Modify Your Code:

Change the Navigation Method:

Adjust the Receiving Screen Logic:
Ensure that the receiving screen (TimeSheetPreviewScreen) is prepared to handle multiple entries. Here’s an important note: if you're dynamically generating screens for each entry, the structure inside the TimeSheetPreviewScreen must allow for displaying a list of names (or other values).

Handling Multiple Values in the Next Screen

To display multiple values on the TimeSheetPreviewScreen, you may want to pass a list instead of a single string. For instance:

Implementing these changes will ensure that your Flutter application dynamically displays all desired values seamlessly. If you encounter more issues or require further explanations, don’t hesitate to ask for help!
