assert(isConsistent());If NDEBUG is defined, the assert macro becomes void. Therefore, such expressions must not have side effects.
(assert (true? (isConsistent)))Tests for true
(assert (isConsistent))Tests for truthy.
assert(isConsistent());If NDEBUG macro is defined, the assert macro becomes void.
var result = isConsistent();
Debug.Assert(result);Debug assertion (removed from Release builds).
It is considered unsafe to call a function directly in a debug assertion because any side-effects in the function won't affect Release builds.

var result = isConsistent();
Trace.Assert(result);Trace assertion (included in Release builds)
assert(isConsistent);Not present in release code (except assert(0); which is special)
assert(isConsistent);Needs to be executed with "--enable-asserts" flag with dart and dart2js commands.
In Flutter it will execute only in debug mode.
dartdevc (development compiler) will execute it by default.

if (.not. isconsistent) stop "Inconsistent state"This will also be checked in a production environment.
let x' = assert isConsistent xWhen x' is evaluted, the condition will be checked and x will be returned.

console.assert(_isConsistent);
(assert (isConsistent))Assertion is always executed.
assert(isConsistent() , "Assertion violation") Cannot be ignored in production environment. One can overwrite the global assert function with an noop, but the evaluation and function call costs remain.
assert(_isConsistent);isConsistent can be any PHP snippet without string quotes.
They will be evaluated only if `assert.active` PHP ini value is enabled, or `assert_options()` is called before.

{$ASSERTIONS ON}
Assert(isConsistent,'isConsistent assertion failed.');Assert() will raise an EAssertionFailed exception if the condition is False.
If you leave out the {$ASSERTIONS ON} (e.g. in production code), the Assert() statement will not be compiled into the program.
