🐞 [Bug] Exception Invalid image dimensions.

[moha-b]

On the home widget, the temperature and date display correctly, but the image does not. I followed the example explanation and here is a code snippet.

What I follow

home_widget/example/lib/main.dart

Lines 118 to 125 in 365f8f9

	HomeWidget.renderFlutterWidget(
	const Icon(
	Icons.flutter_dash,
	size: 200,
	),
	logicalSize: const Size(200, 200),
	key: 'dashIcon',
	),

Dart Code

try {
            print(state.weather.theme.image);
            await Future.wait([
              HomeWidget.saveWidgetData('date', state.weather.date),
              HomeWidget.saveWidgetData(
                  'temperature', state.weather.temperature.toString()),
              HomeWidget.updateWidget(androidName: 'WeatherWidget'),
              HomeWidget.renderFlutterWidget(
                Image.asset(state.weather.theme.image),
                key: 'image',
              ),
            ]);
          } on PlatformException catch (exception) {
            log("Error Sending Data", error: exception);
          }

home_widget/example/android/app/src/main/kotlin/es/antonborri/home_widget_example/HomeWidgetExampleProvider.kt

Lines 38 to 44 in 365f8f9

	val image = widgetData.getString("dashIcon", null)
	if (image != null) {
	setImageViewBitmap(R.id.widget_img, BitmapFactory.decodeFile(image))
	setViewVisibility(R.id.widget_img, View.VISIBLE)
	} else {
	setViewVisibility(R.id.widget_img, View.GONE)
	}

Native Code

 appWidgetIds.forEach { widgetId ->
            val views = RemoteViews(context.packageName,R.layout.weather_widget).apply {
                val widgetData = HomeWidgetPlugin.getData(context)
                val temp = widgetData.getString("temperature","Temperature")
                val date = widgetData.getString("date","Date")
                val image = widgetData.getString("image", null)
                if (image != null) {
                    setImageViewBitmap(R.id.image, BitmapFactory.decodeFile(image))
                    setViewVisibility(R.id.image, View.VISIBLE)
                } else {
                    setViewVisibility(R.id.image, View.GONE)
                }
                setTextViewText(R.id.temperature,temp)
                setTextViewText(R.id.date,date)
            }
            appWidgetManager.updateAppWidget(widgetId,views)
        }

Widget Info

<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/app_widget_description"

    android:updatePeriodMillis="86400000"
    android:widgetCategory="home_screen" />

I understand that the image may be large, but there are no restrictions in the documentation.

The Problem is the image is not appearing even if I resize it

HomeWidget.renderFlutterWidget(
                Image.asset(
                  state.weather.theme.image,
                  width: 100,
                  height: 100,
                ),
                key: 'image',
              ),

The code is no longer throwing an Exception, but the image is still not appearing.
