How do I upload file on click only?

public $import_file = null;

    protected function getFormSchema(): array
    {
        return [
            Section::make('Import User Instructions')
                ->description('Instructions for importing users into the system')
                ->schema([
                    \Filament\Forms\Components\View::make('partials.import-instructions'),
                    FileUpload::make('import_file')
                        ->label('Import File')
                        ->acceptedFileTypes(['text/csv', 'application/vnd.ms-excel'])
                        ->helperText('Upload an Excel (.CSV) file with the required user data.'),
                ])
                ->compact()
                ->collapsible()
                ->footerActions([
                    Actions\Action::make('importUsers')

                ])
                ->footerActionsAlignment(Alignment::End),
        ];
    }

    public function importUsers(): void
    {
        $this->validate([

        ], [

        ]);

        Import::start(
            file: $this->import_file
        );

        Notification::make()
            ->title('File Uploaded')
            ->success()
            ->send();
    }

Perhaps try to provide a type hint for your public property. Or set it with a value.

Regarding that answr how do I deal with Dynamic fields? Because I am currently using a. dynamic field and I have trouble displaying the values since I have to declare a public property For example this one 
  foreach ($this->group_settings_sections as $section) {
            foreach ($section->settings as $setting) {
                $schema[] = \Filament\Forms\Components\Grid::make(2)
                    ->schema([
                        // Left Column
                        \Filament\Forms\Components\View::make('partials.label-description')
                            ->viewData([
                                'title' => $setting->label,
                            ])
                            ->columnSpan(1),

                        // Right Column
                        match ($setting->type) {
                            'point_of_contact' => \Filament\Forms\Components\Group::make()
                                ->schema([
                                    \Filament\Forms\Components\TextInput::make("settings.{$setting->uuid}.name")
                                        ->label('Name')
                                        ->default(Arr::get(group()->setting($setting->shortcode), 'name')),

                                    \Filament\Forms\Components\TextInput::make("settings.{$setting->uuid}.email")

                                ->columnSpan(1),
  foreach ($this->group_settings_sections as $section) {
            foreach ($section->settings as $setting) {
                $schema[] = \Filament\Forms\Components\Grid::make(2)

I’m not sure how this relates to the original question. Did you try to set the type of the property? For example: public string name. I think your error is from setting the property to type void. If you don’t specify a type in php it has to guess. When you set the value to null php thinks you also want the type to be null.

A bit vague, but the dynamic fields looks like this, I am not sure whats the proper way of declaring a property with this one

https://www.honeybadger.io/blog/php-type-hinting/. I found an article on type hinting in php. I think understanding how types work will help you understand the error. Your example still makes php guess what the type is. I don’t think this is the answer for fixing everything in your code but it’s an important concept to understand.
