FlutterFlow Editor fails to render nested Rows correctly while Local Run works as expected #7216

  • I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

In the FlutterFlow editor, a layout containing multiple nested Row widgets is not rendered correctly.

The affected structure is similar to the following:

Column
└── Row
├── Row
│ ├── Text
│ ├── VerticalDivider
│ └── Text
└── Row
├── DropDown
└── Container
└── Blur
└── Icon

When this layout is used, both nested Row widgets fail to render correctly in the editor preview. Instead, the area where these widgets should appear becomes gray, making the editor preview unusable.

However, when the project is executed using Local Run, the UI is displayed correctly and behaves as expected.

This issue appears to affect only the FlutterFlow editor preview, not the generated Flutter application.

Expected Behavior

The FlutterFlow editor should render the widget tree exactly as it appears during Local Run.

Both nested Row widgets and all of their child widgets (Text, VerticalDivider, DropDown, Container, Blur, Icon, etc.) should be displayed correctly in the editor without turning gray or disappearing.

Steps to Reproduce

Yes

Steps to reproduce
Create a blank page.
Add a Column.
Add a parent Row.
Inside the parent Row, add two child Row widgets.
Configure the first Row with:
Text
VerticalDivider
Text
Configure the second Row with:
DropDown
Container
Blur
Icon
Return to the editor.

Result

The nested Row widgets are no longer rendered correctly in the editor. The affected area becomes gray and the widgets are not displayed.

Expected

The editor should display the same layout that appears correctly in Local Run.

Reproducible from Blank

  • The steps to reproduce above start from a blank project.
