Include breakpoint error reason in tooltip when breakpoints cannot be set #5314
Description
With the fix for dart-lang/sdk#56820 / #5157, the breakpoint will no longer be set. The VM returns us a reason:
{
"jsonrpc": "2.0",
"error": {
"code": 102,
"message": "Cannot add breakpoint",
"data": {
"request": {
"method": "addBreakpointWithScriptUri",
"params": {
"isolateId": "isolates/49774056015291",
"scriptUri": "file:///D:/Dev/Test%20Projects/dartcode_5157/bin/dartcode_5157.dart",
"line": "8"
}
},
"details": "addBreakpointWithScriptUri: Cannot add breakpoint at line 8. Error occurred when resolving breakpoint location: No debuggable code where breakpoint was requested."
}
},
"id": "15"
}We should wire this up to the reason field on the breakpoint so that it shows if the user hovers over the grey breakpoint.
