For me the following code works fine, as long as this.state.error === undefined or it is not an empty string.

render() {
  return (
    <View>
      {this.state.error &&

        <Text>
          Error message: {this.state.error}
        </Text>
      }
    </View>
  );
}
If the error state is changed to empty string '', you will have the aforementioned exception: Invariant Violation: Text strings must be rendered within a <Text> component

The reason of that is, when this.state.error === '', the following expression will be evaluated as empty string, i.e., '', and this will cause Invariant Violation: Text strings must be rendered within a <Text> component

{this.state.error &&

  <Text>
    Error message: {this.state.error}
  </Text>
}
When this.state.error === undefined, the expression will be evaluated as undefined, which is what we expect, and it's fine.

I've shot myself in the foot too many times over this, so I'm leaving this
here for the next person not to...

Whenever you see
```
Invariant Violation: Text strings must be rendered within a <Text> component
99% of cases will be caused by using conditional rendering with only && 
instead of ternary ? : statements. Why? Because when your condition
resolves to undefined, there are no components there, as opposed to 
null or an empty array which would have safely showed an empty space 
and save your life from the red screen of hell.
```

Change ALL OF YOUR LOGICAL CONDITIONAL RENDERS into ternary renditions.

ie:

DON'T DO
`widgetNumber === 10 && <MyComponent />`
  
DO DO
`widgetNumber === 10 ? <MyComponent /> : null`
