I just updated to Dart2 and Flutter sdk: '>=2.12.0 <3.0.0' and now this if statement breaks:
decoration: new BoxDecoration(
shape: BoxShape.circle,
color: Colors.blueAccent,
border: Border.all(
color: Colors.blueAccent,
width: 20.0,
style: BorderStyle.solid),
image: new DecorationImage(
fit: BoxFit.cover,
image: myMarkerThumb != 'noImage'
? NetworkImage(myMarkerThumb)
: AssetImage('assets/images/noImageAvailable.png'),
),
),
The argument type 'Object' can't be assigned to the parameter type 'ImageProvider'. ),
I'm just starting with flutter and have no idea where to look else.

This meant it was valid to assign, for example, a function with a parameter of type String to a place that expected a function type with a parameter of dynamic. However, in Dart 2 using a parameter type other than dynamic (or another top type, such as Object?) results in a compile-time error.

A simple workaround you could make in the meantime is just to cast the object.
decoration: BoxDecoration(
shape: BoxShape.circle,
color: Colors.blueAccent,
border: Border.all(
color: Colors.blueAccent,
width: 20.0,
style: BorderStyle.solid),
image: DecorationImage(
fit: BoxFit.cover,
image: myMarkerThumb != 'noImage'
? NetworkImage(myMarkerThumb)
: AssetImage('assets/images/noImageAvailable.png') as ImageProvider,
),
),
