How to dynamically generate Field schemas in Filament v3

Section::make('AQL Report Form')
    ->schema([
        TextInput::make('limitCardNumber')
            ->label('Limit Card')
            ->disabled(true),
        TextInput::make('orderQuantity')
            ->label('Order Quantity')
            ->disabled(true),
        Select::make('stageId')
            ->options($this->stages)
            ->label('Stage')
            ->afterStateUpdated(function (Set $set, Get $get) {
                $this->updateDefects($this->stageId);
            })
            // This is needed for the stateUpdated method to work
            ->reactive(),
    ])
    ->columns(3),
Section::make('Defect List')
    ->schema(function () {
        return $this->defectListSchema;
    })
    ->columns(3)
    ->hidden(function () {
        return $this->hideDefectList;
    })
    ->reactive(),

$schema = [];
$defectCategories = DefectCategory::get()->pluck('category', 'id')->toArray();
if (is_null($this->defectsByCategory)) {
    return $schema;
}
foreach ($this->defectsByCategory as $category => $defects) {
    $sectionSchema = [];
    foreach ($defects as $defect) {
        $sectionSchema = array_merge($sectionSchema, [
            TextInput::make('defectName')->label($defect['name'])->disabled(true),
        ]);
    }
    $schema = array_merge($schema, [
        Section::make($defectCategories[$category])
            ->schema($sectionSchema),
    ]);
}
return $schema;
